Don't usually go for these kind of books - but on the spur of the moment, I bought it from Waldenbooks:
Carvel, the Christmas Cat
It is marvelous. Caution: the prologue is very hard to read, particularily if animal abuse is anywhere in your background. But it sets up the story.
Takes place in 1962 (when a lot of us were teens). The interaction between teens, siblings, parents, is great. The book isn't long and can be read in one long evening.
It's been a while since I've read something that made me cry, then later chuckle, then stupidly sit there laughing all by myself.
Most likely, not suitable for preteens - wouldn't understand teenagers & perhaps too graphic about the abused kitten lost, found & loved.
Highly recommend it & the book is a keeper!
