A Swiftly Tilting Planet Author:Madeleine L'Engle Charles Wallace Murry, a child in A Wrinkle in Time and A Wind in the Door, has grown into an adolescent. The youngest of the Murry children must travel through time and space in a battle against an evil dictator who would destroy the entire universe.
ISBN # is 0374373620, but this is not the hardcover edition.
Read "A Wrinkle in Time" and "A Wind in the Door" before you read this one, otherwise it won't make as much sense. That being said, this is by far my favorite Madeleine L'Engle books!
