I think the idea that in a riddle there are two answers or two doors and that you have to pick the right one is almost sort of delightful to kids who are making so many choices every day and who often don't know for a while if they've made the right one. It's not as if you make a choice and then *ding* you have some sense of "oh, this is perfect and I'm happy" - it's never that simple.

I think that's why I wanted to write about seventh grade. I'd say seventh grade is a time when kids are really exploring a lot and becoming aware of the world around them in a deeper way.

I feel lucky that I read so many books as a kid because I know that no matter how much I appreciate a book now, and I can love a book very much, it's never going to be that childhood passion for a book. There's some element, something special about the way they're reading books and experiencing books that's finite.

Beautiful and fresh, Girl Saves Boy is full of the absolute truth-life is complicated. I could not put it down.
