Finder — Greg Rucka

As a bodyguard, Atticus Kodiak knows danger is part of the job. But he still can't shake his guilt over his best friend's death in their last assignment. As a bouncer at a hard-core club on the Lower West Side, Atticus is responsible for nothing more than keeping the scene under control. Until he sees Erika Wyatt, the teenage daughter of an Army colonel Atticus once guarded. Stalked by a cold-eyed commando fondling a wicked knife, Erika draws Atticus back into the protection business. In a case built on lies, vengeance, and sins of the past, Atticus is pulled into a vortex of treachery and violence, and learns that a promise can be the most dangerous weapon of all....
