Kismet by Sarah Michelle Lynch

“Survival makes animals of us, Ruben. Animals.”
Ruben and Freya have been friends for two years and still don’t know one another very well. Whenever they meet up for a drink, sex with other people is something they openly discuss, but fooling around with each other is out of the question.
Then right out of the blue, everything changes. Freya can’t stand to have him in her life anymore and Ruben is shocked into action, forced to confess his true feelings.
Endless nights of pure, unbridled passion between two people seemingly destined to be together follow. Freya and Ruben are equally closed books, but as their passion unfolds, so do the pages of their chequered pasts.
There is however, one secret so dark and devastating, it could wreck their lives. As their pasts converge, kismet will play a big part in whether they survive or die.
