From a maternal mental health specialist comes an empowering guide to help reshape your internalized expectations and beliefs around motherhood.

Every mom wants to be a good parent―but if you’ve found yourself burned out and overwhelmed trying to be “the perfect mom,” you’re not alone. “We get handed a rulebook of motherhood without realizing it,” says Erica Djossa. “That rulebook comes with an invisible load―a world of mental and physical tasks that keeps us pushing toward perfection while barely being able to breathe.” With Releasing the Mother Load, this renowned parenting specialist shares a guide to help you break free from the crushing burden of unrealistic expectations and reclaim the joy of motherhood while staying true to your own values.

As a therapist and the founder of the Momwell community, Erica has learned how many mothers from all backgrounds and walks of life feel trapped by modern motherhood. Here she dispels the falsehoods our culture has built around what it means to be a mom and shares practical, proven guidance for a more empowered approach to parenting, including:

• What is the Mother Load? Where our expectations come from and why they don’t serve us or our children
• Making the Mother Load visible―the true emotional and physical cost of the many jobs, habits, and beliefs we carry
• Sharing the load―tools to establish strong boundaries, express your needs, and build a support system
• Practical techniques and scripts to help you create a healthy, balanced, and enriching approach to motherhood

“You can chart your own journey in a way that is freeing, feels right to you, and reignites passions and dreams that you thought had died when you began to put everyone else’s needs first,” says Erica Djossa. Here is a life-changing guide for developing a new vision of motherhood that lets you parent more freely and with greater fulfillment―so you can finally release the Mother Load.

From the bestselling author of The Lincoln Highway, A Gentleman in Moscow, and Rules of Civility, a richly detailed and sharply drawn collection of stories, including a novella featuring one of his most beloved characters.

Millions of Amor Towles fans are in for a treat as he shares some of his shorter fiction: six stories based in New York City and a novella set in Golden Age Hollywood.

The New York stories, most of which take place around the year 2000, consider the fateful consequences that can spring from brief encounters and the delicate mechanics of compromise that operate at the heart of modern marriages.

In Towles’s novel Rules of Civility, the indomitable Evelyn Ross leaves New York City in September 1938 with the intention of returning home to Indiana. But as her train pulls into Chicago, where her parents are waiting, she instead extends her ticket to Los Angeles. Told from seven points of view, “Eve in Hollywood” describes how Eve crafts a new future for herself—and others—in a noirish tale that takes us through the movie sets, bungalows, and dive bars of Los Angeles.

Written with his signature wit, humor, and sophistication, Table for Two is another glittering addition to Towles’s canon of stylish and transporting fiction.

Since the publication of the first edition of A South African Renewable Energy Guide for Local Government, the costs related to non-renewable energy generation have increased exponentially, and coal-based energy systems have continued to generate large quantities of dangerous emissions. Conversely, sustainable energy generation has become more cost-effective, and in many instances renewables are now more economically viable than non-renewables. This narrowing gap in costs, coupled with an increased awareness of the environmental benefits of renewables, has greatly stimulated the sustainable energy market.

Over the last several years, metropolitan municipalities have engaged with innovative, cost-effective sustainable energy projects and solutions. Medium and smaller municipalities are beginning to understand the roles and responsibilities of the various stakeholders in the energy sector. They are learning how to work within the confines of the South African national, provincial and local policy, legislative and regulatory frameworks; how to embed renewables within local integrated development plans and strategies; how to utilise appropriate technologies and how to apply financing mechanisms and leverage partnerships for successful project delivery. It is critically important therefore that (particularly) small, medium and rural municipalities continue to explore, and receive capacity-building and support for, renewable and energy-efficient solutions

In line with these developments, this second edition provides useful information and solid examples of how politicians, city managers and government officials, in partnership with communities, can facilitate the adoption of renewable energy systems and technologies to achieve a more sustainable energy future for all.

A tribute to her father, Makaziwe Mandela shares the most definitive portrait of Nelson Mandela to date, revealing the man behind the anti-apartheid movement that changed the world.

One of Time magazine’s Most Important People of the Twentieth Century, Nelson Mandela continues to be a symbol of equality and justice: a Nobel Prize winner, South Africa’s first Black president, and an unrelenting leader in the movement to dismantle racial inequality. Written by his daughter, her story uncovers the family man behind the international peacemaker persona.

This volume presents an extraordinary assembly of historic biography and imagery alongside never-before-published family stories and personal photographs, Nelson Mandela’s letters to friends and family, journal entries written during his incarceration, and a unique collection of rarely seen charcoal drawings and paintings he began at 83 years old. Chapters chronicle Mandela’s childhood growing up in Mvezo, his time in Johannesburg as leader of the African National Congress, the importance of his familial relationships, decades of imprisonment, and his role as president and philanthropist. An enthralling read illustrated by powerful historic imagery, this tome delves into the life of the man that continues to galvanize so many.

But when an alcohol-fuelled night out leaves Kate and Trevor accidentally hitched, her plans are officially out the window. To make matters worse, Trevor has decided he wants Kate back, and won’t sign the annulment papers until she agrees to go on three last dates with him.

With her fairy tale wedding just days away, Kate is determined to fight her growing feelings for Trevor. But in the scorching heat of Sin City, is it time for her to tear up the rule book, and finally take a gamble on love?

From Willow Smith and Jess Hendel comes a powerful and groundbreaking historical epic about an African warrior in the world of the Vikings.

Lore, legend, and history tell us of the Vikings: warrior-kings on epic journeys of conquest and plunder. But the stories we know are not the only stories to tell. There is another story, one that has been lost to the mists of time: the saga of the dark queen.

That saga begins with Yafeu, a defiant yet fiercely compassionate young warrior who is stolen from her home in the flourishing Ghanaian empire and taken as a slave to a distant kingdom in the North. There she is thrust into a strange, cold world of savage shield maidens, tyrannical rulers, and mysterious gods.

And there she also finds something unexpected: a kindred spirit. She comes to serve Freydis, a shy princess who couldn’t be more different than the confident and self-possessed Yafeu.

But they both want the same thing: to forge their own fate. Yafeu inspires Freydis to dream of a future greater than the one that the king and queen have forced upon her. And with the princess at her side, Yafeu learns to navigate this new world and grows increasingly determined to become one of the legendary shield maidens.

For Yafeu may have lost her home, but she still knows who she is, and she’s not afraid to be the flame that burns a city to the ground so a new world can rise from the ashes. She will alter the course of history - and become the revolutionary heroine of her own myth.

Battery Voltage Indicator
When the light is turned on, the built-in power indicator under the stainless steel side switch will show different color light to indicate remaining battery voltage:While battery voltage > 10.2V, blue light turn on and last 3s.
While battery voltage 9.6V-10.2V, purple light turn on and last 3s.
While battery voltage 8.7V-9.6V, red light constant-on.
While battery voltage < 8.7V, the light turn off authomatically.
* Low voltage warning
When the battery voltage level drops below the present level, the light is programmed to downshift to a lower brightness level until lowest output is reached. When the battery voltage level still drops low under lowest output, it will shut off authomatically.
Intelligent Overheat Protection
Advanced intelligent temperature regulation technology allows MK38 to dynamically adjust output performance according to its body temperature.The light will accumulate a lot of heat when you use it at high-output levels for extended periods. When the light reaches the temperature of 65°C or above, the light will automatically step down its output to reduce the temperature. at the same time we also make more premium cooling fins on flashlight head and built-in duable-row fans to blow effectively these cooling fins through the outside to protect flashlight overheat.
* Note: DO NOT submerge the flashlight into any liquid when it is hot. Doing so may cause irrepareable damage to the light due to the difference of air pressure inside and outside of tube.Note: We also high recommend the oridinary users to purhcase Samsung 40T unprotected flat-top 21700 batteries or Modell P42A unprotected flat-top 21700 batteries to drive MK38.

Advanced intelligent temperature regulation technology allows MK38 to dynamically adjust output performance according to its body temperature.The light will accumulate a lot of heat when you use it at high-output levels for extended periods. When the light reaches the temperature of 65°C or above, the light will automatically step down its output to reduce the temperature. at the same time we also make more premium cooling fins on flashlight head and built-in duable-row fans to blow effectively these cooling fins through the outside to protect flashlight overheat.
* Note: DO NOT submerge the flashlight into any liquid when it is hot. Doing so may cause irrepareable damage to the light due to the difference of air pressure inside and outside of tube.Note: We also high recommend the oridinary users to purhcase Samsung 40T unprotected flat-top 21700 batteries or Modell P42A unprotected flat-top 21700 batteries to drive MK38.

Battery Voltage Indicator
When the light is turned on, the built-in power indicator under the stainless steel side switch will show different color light to indicate remaining battery voltage:While battery voltage > 10.2V, blue light turn on and last 3s.
While battery voltage 9.6V-10.2V, purple light turn on and last 3s.
While battery voltage 8.7V-9.6V, red light constant-on.
While battery voltage < 8.7V, the light turn off authomatically.
* Low voltage warning
When the battery voltage level drops below the present level, the light is programmed to downshift to a lower brightness level until lowest output is reached. When the battery voltage level still drops low under lowest output, it will shut off authomatically.
Intelligent Overheat Protection
Advanced intelligent temperature regulation technology allows MK38 to dynamically adjust output performance according to its body temperature.The light will accumulate a lot of heat when you use it at high-output levels for extended periods. When the light reaches the temperature of 65°C or above, the light will automatically step down its output to reduce the temperature. at the same time we also make more premium cooling fins on flashlight head and built-in duable-row fans to blow effectively these cooling fins through the outside to protect flashlight overheat.
* Note: DO NOT submerge the flashlight into any liquid when it is hot. Doing so may cause irrepareable damage to the light due to the difference of air pressure inside and outside of tube.Note: We also high recommend the oridinary users to purhcase Samsung 40T unprotected flat-top 21700 batteries or Modell P42A unprotected flat-top 21700 batteries to drive MK38.

Battery Voltage Indicator
When the light is turned on, the built-in power indicator under the stainless steel side switch will show different color light to indicate remaining battery voltage:While battery voltage > 10.2V, blue light turn on and last 3s.
While battery voltage 9.6V-10.2V, purple light turn on and last 3s.
While battery voltage 8.7V-9.6V, red light constant-on.
While battery voltage < 8.7V, the light turn off authomatically.
* Low voltage warning
When the battery voltage level drops below the present level, the light is programmed to downshift to a lower brightness level until lowest output is reached. When the battery voltage level still drops low under lowest output, it will shut off authomatically.
Intelligent Overheat Protection
Advanced intelligent temperature regulation technology allows MK38 to dynamically adjust output performance according to its body temperature.The light will accumulate a lot of heat when you use it at high-output levels for extended periods. When the light reaches the temperature of 65°C or above, the light will automatically step down its output to reduce the temperature. at the same time we also make more premium cooling fins on flashlight head and built-in duable-row fans to blow effectively these cooling fins through the outside to protect flashlight overheat.
* Note: DO NOT submerge the flashlight into any liquid when it is hot. Doing so may cause irrepareable damage to the light due to the difference of air pressure inside and outside of tube.Note: We also high recommend the oridinary users to purhcase Samsung 40T unprotected flat-top 21700 batteries or Modell P42A unprotected flat-top 21700 batteries to drive MK38.
