All contract killer Lachlan Kane wants is a quiet life. But when he botches a job for his boss's biggest client, Lachlan knows he'll never claw his way out of the underworld. At least, not until Lark Montague offers him a deal: use his skills to hunt down a killer and she'll find a way to secure his freedom.

The catch? He has to marry her first. And they can't stand each other.

Indie singer-songwriter Lark may seem like sunshine and glitter personified but she has her own secrets hiding in the shadows. With her formidable family in a tailspin and her best friend's happiness on the line, she's willing to make a vow to the man she's determined to hate, no matter how tempting the broody assassin might be.

As Lachlan and Lark navigate the dark world that binds them together, it becomes impossible to discern their fake marriage from a real one. But it's not just familiar dangers that haunt them. There's another phantom lurking on their doorstep . . . And this one has come for blood.
