The Last Honest Horse Thief — Michael Koryta

A boy comes of age among a family of grifters in this powerful story from a New York Times�"bestselling “master” (Stephen King).
 
Never knowing a real home, Markus Novak's only constant in life is his passion for paperback westerns. The child of a family of outlaws, he moves through the West town by town with his mother and two uncles, staying in a place just long enough to run a short con and move along.  After one job goes south and his mom gets locked up, Markus finds himself in the foster care of a rancher and his wife -- with whom he's strangely comfortable, yet torn by loyalty to the family he's lost.
 
To distract himself, he spends his days working the farm and his nights fixing a rusty old '55 Chevy. Then he discovers a note from his uncles hidden in a book at a local pawnshop and learns that they are hiding out in a mountain town near Yellowstone. Restoring the car soon becomes Markus's only hope of finding them, and maybe finally finding himself, too.
