Several new interactive titles offer visual and musical excitement. Rosemary Wells's perennial stars return for a postal adventure in Bunny Mail: A Max & Ruby Lift-the-Flap Book. Readers lift flaps to peer inside each missive. Max's summertime letter to Santa (marked only with tire tread marks, to indicate his desire for a new scooter) instead arrives at Grandma's house (thanks to an enterprising postman). Confused, she sends him back a picture of a tractor. The misunderstanding is finally corrected in this adorable addition to the series. .
