Munro invites readers in rhyme to lift ten big single- or double-flap doors to look for objects inside. But that’s only the beginning, as each opens onto a room or vista chock full of clothing, food, tools, gear, knickknacks, an occasional glimpse of a human figure for scale, and, best of all, even more doors. Given chances to peer into a firehouse and a spaceship, a barn, a stuffed refrigerator, a doctor’s office, and similarly enticing scenes, children will pore delightedly over each exactly drawn, instantly recognizable detail. Munro tucks a hat and an apple into each view, and closes with “a door of a different kind— / to fantastic worlds that will open your mind.” It’s a storybook, with a medieval landscape inside. Never have the pleasures of discovery been more generously fulfilled. (Picture book. 4-8)
