The first Saturday in July. A missing woman. The number seven carved into her door. The countdown has begun . . .

Detective Micki Dare is a seasoned, no-nonsense cop. She doesn't need a partner, especially an irreverent charmer like Detective Zach Harris, who's fresh out of an 'experimental' FBI training programme. And Micki's assignment, to keep Zach alive while he fights crime using his special skills, is not what she signed up for. But the decision's been made and there's nothing she can do about it.

Micki soon realises that there's more to her partner than meets the eye - and there's more at stake than just catching bad guys and closing cases. Because there's a new kind of evil lurking, something more cunning than she's ever encountered before. And she and Zach may be the only ones who can stop it.

As another victim goes missing and the darkness closes in, Micki acknowledges a terrifying truth: they might not make it. This time the evil they're facing might destroy them all . . .

Full of twists and drama, The Final Seven is a compulsive and heart-pounding thriller that will keep you on the edge of your seat until the very last page.
