A reviewer for "The Atlanta Journal-Constitution" wrote that the story is "a touching evolution, one that Haddon scripts with tenderness and care... a unique window into the mind of a boy who thinks a little differently, but like many kids his age, doesn't quite know how to feel." Professor Roger Soder called it "visceral" and a "delightful story," declaring, "All of us in our Spokane Book Club are special education professionals and so have considerable experience with kids with this disability, and we found the story believable."
