When Kirsty and Ryan broke up, Kirsty didn't just lose the man she loved. She lost the life she'd built around him. The future they'd promised each other.

But now he's left her for Charlotte. Again. The woman his family always preferred.

And Kirsty is done waiting. Done hoping. Done being the one left behind.

This time, she wants revenge.

Consumed by jealousy, Kirsty becomes obsessed by Charlotte, turning into a stalker as she digs into her life and uncovers secrets and lies buried deep within Ryan's family. Lies that involve her.

But the more Kirsty learns, the more dangerous her obsession becomes.

Because revenge was one thing.

But murder is something else entirely.
