Out of the Blue — J.R. Carroll

The shockingly violent death of his wife was no accident. And Dennis Gatz knows it.

But the cops aren't interested. Gatz is a loose cannon who couldn't handle the force. No longer one of them. No longer worth the trouble.

But trouble's on the way. Someone's out to get Dennis Gatz and he can't wait to meet them. Head on.

This time it's personal. This time he'll do anything for revenge. And the best revenge comes out of the blue.
