I'm on the 5th book of the Wrinkle in Time series right now. I'd never read these books as a child and I'm forever searching for something challenging, yet age appropriate for my gifted kiddo. These are not it. Lol... I know many people love these books but I don't really see the hype (please don't strike me dead! lol). Still I'm glad to have finally crossed them off my To Be Read list!
