I read kids books. Not little kids books, but "young adult" books. And I enjoy them.
Have you read the Sisterhood of the Travelling Pants?? Possibly you have heard of the movie?? There are 4 books in all, and they are very good. You should read them.
I also read adult books (no, not ADULT books......grown up books). My new favorite is Jodie Picoult. Her books are about very interesting issues--a child's legal right to refuse to donate an organ to a sibling, a woman who finds out as an adult that the father she loves so much kidnapped her as a small child, etc, etc, etc. Really in-depth and interesting.
I also love Clive Cussler, John Grisham, Michael Crichton, etc.
So I read big kid AND little kid books.
