Sirens by Joseph Knox

The breathtakingly propulsive and stunningly assured debut thriller, perfect for readers of Tana French, Don Winslow, and Dennis Lehane

The mission is suicide.
Infiltrating the inner circle of enigmatic criminal Zain Carver is dangerous enough. Pulling it off while also rescuing Isabelle Rossiter, a runaway politician's daughter, from Zain's influence? Impossible. That's why Aidan Waits is the perfect man for the job. Disgraced, emotionally damaged and despised by his superiors. In other words, completely expendable.

But Aidan is a born survivor. And as he works his way deep into Zain's shadowy world, he finds that nothing is as it seems. Zain is a mesmerizing, Gatsby-esque figure who lures young women into his orbit--women who have a bad habit of turning up dead. But is Zain really responsible? And will Isabelle be next?

Before long, Aidan finds himself in over his head, cut loose by his superiors, and dangerously attracted to the wrong woman.

How can he save the girl if he can't even save himself?
