This nonfiction ode to boats features six kinds of workers and their boats—a patrol boat, a tugboat, a car ferry, a lobster boat, a lifeboat, and a fireboat—with important parts properly labeled. The answer to each inquiring refrain lies under a gatefold, engaging the reader in an informative guessing game. With lyrical (and factual!) text by New York Times–bestselling author Toni Buzzeo, and the stylized art of Tom Froese, this sturdy board book is perfect for curious and playful young readers. 16 pgs.
