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.
