Ex-con Jason Carr has faced down the toughest thugs in Cardiff, but being assistant to a brilliant, eccentric hacker who hasn't been outdoors in ten years has its own challenges. Still, he and Amy Lane can solve cases even the cops can't crack. And when a corpse washes up on a beach, Jason can't resist chasing the clues—or defying Amy by infiltrating the very gangs he once escaped.

Amy is distraught when Jason's pursuit gets him framed for murder. He's thrown back in prison where he's vulnerable to people who want him dead. He needs Amy to prove his innocence. Fast.

But Amy hasn't been honest with him—her panic attacks aren't getting better. And now, with everything that makes her feel safe ripped away, she must stand alone, using her technological skills to expose a baffling conspiracy and a new kind of online crime. Can she clear Jason's name before danger closes in?
