Two books by Blue Balliett:
Chasing Vermeer and The Wright 3.
I read only book #1 and thought it was great, especially great for gifted kids. Ms. Balliett used to be or still is a teacher at the gifted school.
Also, if you have a girl who plays violin, who has some jewish blood in her, get The Mozart Season by Virginia Euwer Wolff. I could not put it down. Even my mathematically gifted middle school age son enjoyed this book. And it made him want to practice violin more! ( a very, very positive bonus I might add)
