This endearing friendship story about a boy and his dog from a Pulitzer Prize-winning writer gently explores a timeless question: who's really in charge? Meet Sid. He's an ordinary kid. He's far from perfect. But to Murphy, Sid's faithful dog, Sid is the whole world. Murphy thinks Sid is the absolute best--and that he's in charge of everything.
