As I've gone through parenthood, I've chosen to listen/read books that my children like. It's kinda a bonding thing, and they've liked it. It's been good for me also.
Last night a good friend asked me about books that might interest her 10 year old daughter. She likes books that have a strong female character.
The first books that came to mind for me were written by Tamora Pierce. The series that I absolutely loved was the "Protector of the Small". This series follows a young woman through knighthood.
Another book series that I liked that had strong female characters, believe it or not, is the "House of Night" Series - I love the relationship between Zoey and her grandmother and also it's kinda a kick ass Vampire series.
Madeline L'Engle's "Time" Quintet was my favorite as a young reader, still a great read as an adult.
Orson Scott Card is by far my favorite author these days - Pathfinder and Lost Gate would be good boy picks along with the "Ender's Game" series.
