The invitation to her school reunion couldn't have come at a better time for Chloe Flynn. Divorced, broke and bored at work, she's living a life her teenage self would hate. Turning the clock back fifteen years might be just what she needs to wipe the slate clean and start again. And then there's the chance she'll bump into Nathan Blake, the one she still regrets letting get away...

Back at her elite private school, Chloe sparkles as she reunites with old friends and long-forgotten love interests. And then, just as she'd hoped, there's Nathan, more handsome than ever before. Even better, he's single too, and seems to be just as keen to make up for lost time...

But as the evening progresses, Chloe can't help feeling that something's not quite right--that she's not the only one who's come here for more than just a party. When the secrets of the past start to emerge and the reunion takes a sinister turn, it's clear that nothing is what it seems--and nothing will be the same again.
