Don't Skip Out on Me by Willy Vlautin

Horace Hopper has spent most of his life on a Nevada sheep ranch, but dreams of something bigger. Mr. and Mrs. Reese, the aging ranchers, took him in and treated him like a son, intending to leave the ranch in his hands. But Horace, ashamed not only of his half-Paiute, half-Irish heritage, but also of the fact his parents did not want him, feels as is he doesn't belong on the ranch, or anywhere. Knowing he needs to make a name for himself, Horace decides to the only loving home he's known to prove his worth as a championship boxer. Read a sample.
