Private security operator Ryan Lock and his partner, retired US Marine are back in the brand new novel from internationally bestselling author, Sean Black. An isolated school for troubled teens. A series of mysterious deaths. A father frantically trying to rescue his daughter before it's too late.
But when the law won't listen, who can he turn to?
Praise for Sean Black's Ryan Lock series:

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