Barracuda

"Fishing for barracuda from a kayak in the Florida Keys. That's what Jim Webb thinks this resort vacation with his grandfather should be about. Except the dying resort owner holds the key to legend about a generations-old crime. A crime that is worth way too much to those who want the legend to be true.

And along the way, he learns an important truth about himself and his own past"--Amazon.com.
