Rumble! Roar! Dinosaurs!

Most of Reinhart's pop-up books hover around $30, so this paperback pop-up is a serious bargain (coloring book pages that open and close the book only add value). Inside, kids will find pared-down versions of Reinhart's trademark pop-ups that still show a good deal of personality and ingenuity. In one spread, readers pull down on a cloud to reveal a green pteranodon keeping an eye on her "precious eggs," and in the final scene, "Armored Ankylosaurus fights back" against a T. rex; tugging its head causes its "knobby tail" to swing toward the aggressor.
