Marvel and a wonder

"In the summer of 1995, a Korean War vet struggling to raise his sixteen-year-old grandson on a farm in southern Indiana receives a mysterious gift--a beautiful quarter horse--that upends the balance of their lives. The horse catches the attention of two meth-dealing brothers who steal and sell the animal. Grandfather and grandson pursue the ruthless criminals across the bleak heartland, all the while confronting the misperceptions [sic] of their own troubled relationship."--Back cover.
