A Wrinkle in Time by Madeleine L'Engle
I'm on the wrong side of history here, but I didn't enjoy 'A Wrinkle in Time'. I'd read it before (at too old of an age) but had forgotten everything except the back garden and an alien planet.
Meg Murray and Calvin are great characters, but there didn't seem to be enough of a story for them to move within. I liked the Mrs....I loved the imagination...but it left me cold.
It's not you, its me Madeleine L'Engle.
