Beep! Beep! It's Halloween, and Little Blue Truck is rumbling down the road picking up friends for a costume party. Every stop brings another disguised passenger, and every flap answers the only question that matters to a toddler: who is under that costume? Keep lifting to the end to find out whether Blue himself dressed up.

Alice Schertle's bouncy rhyme reads aloud the way a good engine idles, and Jill McElmurry's painted pictures give the farm road just enough dusk and glow to feel like the real night without being scary. It is the number one New York Times bestselling truck for a reason: the little blue pickup has manners, patience and friends who show up.

A big, sturdy lift-the-flap board book, nine inches wide, with flaps that stand up to enthusiastic re-reading. This one gets requested nightly from late September on, so park it somewhere easy to reach.
