These were some of my favorite books growing up!!
Later on, I was surprised that tesseracts exist - and at some of the other information I had unknowingly absorbed from the books
I read a study somewhere about why there are so few female protagonists in children's books/sci fi books: Basically, the study said that while girls don't mind reading stories with boys as the main characters, it is harder to get boys to read books where the girl is the main character... Our society hasn't come as far as we'd like to think...
Wonder how that relates to the most recent phenom: "Hunger Games." Is it mostly girls that are interested in this movie??? Or does it captivate the boys as well due to its' premise of fighting to the death?
