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."
