Promising Young Woman meets High Fidelity in the dark and twisty new thriller from the bestselling author of The Sunday Girl, The Strangers We Know and The Paris Affair.

A bad day at work. A drunken night. A rogue Instagram follow. That’s all it takes to ruin a life …

The question is, whose life will be ruined? When Billie wakes up in a strange guy’s bed, her first thought is: what happened last night? She can't even remember meeting him. And how the hell did she get to Coney Island?

Then reality bites and the memories flood in – the reason she was in that bar, drinking to start with: today she's going to get fired. Because yesterday her law firm lost a big case: Samuel Grange v Jane Delaney. And it looked like it was her fault.

It wasn't. Yet now Samuel Grange is free to drive off into the sunset in his stupid Porsche and do it all again to another woman. And all Billie can think is: What about the next girl? And the one after that? But there is nothing she can do to stop him.

Unless ... She could expose the truth about him on her own. Then everyone would see what he was really like. And he wouldn't be able to do it again.

The problem is, the only way to protect the next girl is to become the next girl. And, well, that could be a little risky ... even deadly.
