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.

Sid loves Murphy right back, but he can't help but wonder what Murphy would think if he realized the truth: Sid's just a kid, and Murphy's just a dog, and neither one can control the world.

This deceptively simply picture book is the perfect start to a discussion about a subject seldom seen in children's books—the nonthreatening feel of a world based on fact and reason, and not faith.
