Dr. Lena Schuett designed a few simple lessons in seduction. But as the lines between "clinical" and "crave" begin to blur, Lena realizes she's breaking the most important rule of all; Don't fall for your best friend. So how do you go back to being just friends when you've already tasted forever?

Viv (Lena) grew up in a prominent family, raised to be poised, composed, and sensible. Everything in her life was neatly laid out: university, connections, a promising career at her own bridal boutique. She was set to marry Ben (Alek), the son of her parents' longtime friends. A good man. The kind of man no one could find a reason to say no to. They fit. Or at least, they looked like they did. And then came Mira (Miu). They were worlds apart. Different generations, different ways of talking, different ways of falling in love. Mira arrived like a small storm; stubborn, blunt, and impossibly charming. She didn't ask to be part of Viv's life, but it was in that unexpectedness that Viv found something she hadn't realized was missing: curiosity, a sense of being alive. And, more confusing than anything, a desire that didn't play by the rules she thought she understood.
