These books have been around for a while, and there's a good reason. They're great! I first read Clementine when Z was far too young to read; I picked it up from the library because Marla Frazee also illustrated this, which is one of our very favorite picture books.
Z received these three books for Christmas from Nana and Papa. She read the first with Papa, and the next two by herself in two afternoons. She gives them two thumbs up. (And I give the illustrations two thumbs up, too.)
