I'm a major re-re-re-reader. I have some old favorites I've read dozens of times. "The Changeover" by Margaret Mahy is one of these. I still remember picking it out at the library near where I grew up. There have been many covers over the years since this was first published, but this was the cover from the edition I first read and, years later, bought to read over and over again. My copy looks no where near this clean and fresh though.
