Every day over 20 million litres of brackish water are pumped out of the ground near Jeddah in Saudi Arabia and passed through thin sheets of cellulose acetate known as reverse osmosis membranes before being used as part of the city's water supply. In St Maurice les Chateauneuf, France three million litres a day of ground water are ultrafiltered to supply the city and on test sites in Australia settled sewage is being disinfected by being passed through microfiltration membranes. Many of the foods we eat and beverages we drink have used membranes during their processing. Orange juice can be concentrated by membranes to make a concentrate which retains more of the flavour than does evaporation. Milk can be concentrated slightly by means of a membrane before making a cheese in a process which produces no whey. Gases rising from the ground in a waste tip can be piped away and the carbon dioxide separated from the methane by a membrane process allowing the methane then to be used as a fuel, simultaneously saving energy and reducing the greenhouse effect since methane is more effective as a greenhouse gas than carbon dioxide.

Ghosts aren't the only thing that can haunt you... Nolan and Harley have been in paradise for the last year, head over heels in love. When Nolan proposes and they find out Harley is expecting, it seems they both will have everything they ever wanted. Or will they? Nolan's kept the horrors of his past locked away. After all, he has Harley and Finley's Pub is doing great. None of it matters anymore, right? But when the news of nuptials and babies has the opposite intended effect with his estranged mother, the ghosts of his past come rushing back, and the memories of them are terrorizing him nightly.

Trying to piece together the events surrounding Brody's death proves to be a daunting task, but Harley can't give up. Brody won't let her. He is still in the apartment with her, trapped in limbo until she finds his killer. But he's not waiting for revenge. Harley's next.

**Not for readers under the age of 18+. Contains language, explicit sex, and adult situations.** Kieran Donovan has always been a doormat to the women in his life. Begging his wife not to leave after finding her in bed with not one-but five men-only provides further proof of that. In need of an escape from an empty house and a broken heart, Kieran heads to Midtown to see his estranged brother, Liam. There he meets Shayne Wickham, Liam's best friend. Shayne's dark and sexy with a wild streak a mile long and a sexual appetite for things Kieran's never even dreamed of doing. But after an intense, and all too brief encounter, he's more than willing to learn. Despite the usual safeguards Shayne keeps around herself and her own wounded heart, she finds herself more than willing to show him the ropes...and the floggers...and the paddles. Kieran's never seen himself as dominant in any aspect of his life. But when Shayne submits herself to him, it ignites an inner strength and hunger he never knew he had-and feelings Shayne didn't know she could have. So used to keeping others at an arm's length, the ease with which she finds herself trusting Kieran is both exciting and unsettling. Could Kieran be someone she could finally trust her heart to-or will he leave her scarred like everyone else? Just another mark on her skin.

Will she, Nolan, or anybody else be able to stop it before it's too late? Or will the Harley they know and love be lost to them forever?

As long as Aggie Walker's heart still belongs to him, he's destined to remain in limbo, watching over her. But when her family decides to send her to Scotland for the summer and she meets Camden MacTavish, it seems despite their constant head-butting that there may be something more between them. That is, if she is willing to let Camden in. As Aggie finds herself torn between her lover lost and her lover anew, it becomes clear that she cannot hold on to both. If she decides to let Camden into her heart, she will have to let Brody go. And if she can't let Brody go, she risks losing Camden-and a second chance at love. Forever.

Brody Walsh's life is left in disarray when his girlfriend is found brutally raped and murdered. But it completely shatters when his best friend, Nolan is arrested for the crime.

But as the media and the prosecutors close in on Nolan, ready to convict him for a crime he didn't commit, Brody will be forced to make a choice. A choice that will lead to his untimely death.
