Bounty hunter Luke Jensen has always relied on his guns, his brains, and his guts to bring in the deadliest outlaws in the West. But when a family needs his help, he'll have to use something else: his heart...

Luke Jensen has seen some sorry looking bounties in his time, but this one takes the cake. A wanted poster is offering a reward of one dollar and forty-two cents—plus one busted harmonica—to capture Three-Fingered Jack McKinney. Turns out, McKinney's twelve-year-old son Aaron wants revenge on his daddy for abandoning him and his mom. The reward is all the money Aaron can scrape together. Luke can't say no to the poor boy—or his beautiful mother—so he agrees to go after McKinney and his bank-robbing gang.

Good deeds, however, are like good intentions—the road to hell is paved with them. And when Aaron McKinney decides to tag along, it puts Luke in the middle of a father-and-son reunion that's life-or-death, blood-for-blood, and kill-or-be-killed...
