Bobby Trane surprises his Montana church one Sunday by not showing up. That's usually not a big deal, except when you're the priest. Tired of blank faces, complainers and cell phones ringing during his sermons, Bobby follows the lead of a mysterious letter he receives and takes off to save the world. He is guided to the tiny South Dakota town of Buffalo Gap where sinning is aplenty. With a den of drug-dealing Satanists on one side of town, an outlaw motorcycle gang on the other side, and a pretty, young bar owner trying to make ends meet in the middle, Bobby falls hot on the trail of a local ranch girl who's been missing for almost a year. Meanwhile Bobby's boss dispatches the church's secret POWA team that specializes in finding Priests Out Wandering Around. Fathers Tyler and Simon venture into the most sinful places they guess Bobby may have gone. From the oil fields of North Dakota to the Sturgis Motorcycle Rally they encounter all kinds of sinners and saviors, but none named Bobby Trane. The POWA duo's search mission turns into a rescue mission as they try to find Bobby before the town (and Bobby) go up in smoke. While Bobby talks a tough parable, he also packs a mean punch -- just ask the local drug dealers. He vows not to leave Buffalo Gap until the missing girl is reunited with her father and the town with no churches or dogs finally has at least one of each. * This paperback version also includes "Zoo Falls," a short novel previously published only in e-book.
