I have FOUND the book!! Fancine Pascal (duh) created the series, and Joanna Campbell wrote the books, and the YA book series is called CAITLIN. Because Google hates my misspelling with a Y. brandil is the WINNER for knowing her name.
Here they are! *does a happy wriggle of CLOSURE* (Um, let's not talk about how I may be ordering them, okay?)
...or how I checked this book out every month from the library in 6th grade. :D
