But when the law won't listen, who can he turn to?

The seventh novel in the internationally bestselling series of thrillers from Sean Black.

"This series is ace. There are deservedly strong Lee Child comparisons as the author is also a Brit, his novels US-based, his character appealing, and his publisher the same." - Sarah Broadhurst, The Bookseller

"This is a writer, and a hero, to watch." - Geoffrey Wansell, The Daily Mail 

"Black's style is supremely slick." - Jeremy Jehu, The Daily Telegraph 

"The pace of Lee Child, and the heart of Harlan Coben." - Joseph Finder, New York Times Bestseller (Paranoia, Buried Secrets) 
"The heir apparent to Lee Child" - Ken Bruen, Internationally Bestselling Author of The Guards 

'Ryan Lock (is) a protagonist tough enough to take on the Jacks of this world (that's Bauer and Reacher)' - Russel McLean

'Black's star just keeps on rising.' - Evening Telegraph
