Once the Greeks forced their male gods upon the world, the belief in the power of women was severed. For centuries it has been thought that the wisdom of the high priestesses perished at the hand of the patriarchs-but now the ancient Book of Sophia has surfaced. Its pages contain the truths hidden by history, and the sacred knowledge for the coming age. And it is looking for Skylar Southmartin. Busy picking up the pieces after her mother's untimely death and trying to finish her veterinary degree, Skylar has no idea that she is the link between four mystical women in her life, and the perfect storm the Great Mothers have been waiting for. Meanwhile, she's just reconnected with the first and only love of her life, Argan-but Joshua, a dangerous, irresistible stranger, threatens to ruin everything she's trying to build. Amidst unraveling family secrets that shatter her views of the world and call into question everything she's ever known, Skylar must fight off Joshua's maddening pull and get a handle on her own budding powers-before it's too late.

Skylar Southmartin is not the naïve girl she was a short year ago. She’s made some mistakes and learned a few secrets to life, all the while clinging to the faith her mother instilled in her as a child . . . in herself. And now that she has discovered her life’s purpose within the pages of the ancient Book of Sophia, she knows what she must do: restore a vital memory to the Akashic Library, located deep within the Underworld of Earth. This library is sought after by many who are aware of its existence, for they know the future of human potential rests at its core. Meanwhile, Devlin Grayer has been elected as the 46th President of the United States and his wife, Milicent, is miserable in her new role as First Lady—especially because the Great Mothers have asked Milicent to use her new status to help their cause, and she has no interest in tackling that task. With the help of friends in the unlikeliest of places, Skylar’s journey reveals the significance of the darkness within all of us, and its potential to save or destroy the most precious part of us all: our soul.

This final installment of the Equal Night trilogy will put Skylar to her biggest test to date. After Magus takes her through the alchemical door in the Quine library, she quickly remembers her strange surroundings and the reason she's been brought back to the First Age. Here, she will have to rely on her own magic to navigate the overlapping timelines that will allow her to rewrite history. But if she's not careful, she could destroy it completely. Back home, it will take every one of Skylar's loved ones to execute Ocean's plan, and Argan has the biggest role among them: the impossible task of retrieving Skylar home from the past. Luckily, it's something he's been training for his entire life. Meanwhile, a woman now sits in the Oval Office, the corrupt scaffolding of the US government collapsing around her. Mica Noxx has a vision for the US, one that returns it to the original intention of the Founding Fathers. With Skylar held in the First Age and Mica planted in current day, they have one shot to banish the darkness that's held control for centuries, and return the United States to a trajectory toward its true destiny: becoming the New Atlantis.
