SLEEPING UGLY by Jane Yolen
Plain Jane has a heart of gold -- but her face is as homely as her nose is long. Princess Miserella, on the other hand, is a beautiful princess with a heart of stone. In this droll twist on the classic fairytale, the kiss-bestowing prince learns that beauty is indeed only skin deep.
This is an "early reader," which from writing Ling and Ting (though this is maybe a smidge older) I learned is no easy thing to do well. So, this book is quite impressive to me; the story seems effortless, which is the mark of a truly great author. Of course, Jane Yolen is perhaps the modern Queen of Children's Literature with bazillions of acclaimed titles from poetry to graphic novels, but this is my favorite!
