This book is about a girl named Polly O'Keefe, who,

while visiting her grandparents discovers a

special time travel gate which she can sometimes

go through. After a couple of visits to the past

(about 3000 years ago)she tells her grandparents'

friend who has also gone through the gate, what

she has done. This frightens both him and her

grandparents because what would happen if what

they were doing would change the future? This book

is a very suspenseful sci-fi thriller and I think

that no matter what kind of book you like you'll

love this one! I would give this book a 5 out of 5

stars because normally I don't enjoy reading but I

couldn't seem to put this one down. Madeleine

L'Engle is a very talented writer and here is a

list of some of her other books that you will also

enjoy: The Arm of the Starfish, A House like a

Lotus, Dragons in the Water, A Swiftly Tilting

Planet, and my all time favourite book A Wrinkle In Time.
