This nonfiction follow-up to Whose Tools? features six kinds of trucks—a utility truck, a fire truck, a snowplow, an ambulance, a crane, and a broadcasting truck—with five different parts of each truck properly labeled. The answer to each inquiring refrain of “Whose truck is this?” is revealed under a gatefold, engaging the reader in an informative guessing game about trucks and their operators. With lyrical (and factual!) text by New York Times bestselling author Toni Buzzeo, and the expertly stylized art of Jim Datz, this sturdily constructed board book is perfect for curious and playful young readers.
