In the farming town of Riverside in Washington, Toby Fuller is feeling more alone than ever. Nothing Toby did was ever good enough for his father, but he never expected his father to leave, to abandon him and his mother forever. He loses hope, until a scruffy golden retriever called Buddy follows him home from school.

Though he’s struggling to walk, Buddy matches Toby step for step, never taking his eyes off him, as if Toby is all he needs in the world. And from that day on Buddy never leaves Toby’s side.

Buddy shows Toby a loyalty that he has never known. But then disaster strikes and Toby’s life is changed forever. Will Buddy be able to give Toby the strength he needs to carry on?
