I had no idea how it was going to go and it ended up being a really surprising experience.
In case you haven't heard of this book before, its a children's book, like age 11 and up. It's a classic and it won the Newberry Medal in 1963.
It's about a girl, her brother, and a friend who go on a journey together after meeting this stranger. It delves into the idea of time and space and it's chock full of metaphors and super cool ideas. All I can say without giving things away is that you really won't expect what happens.
I really enjoyed this book. And its part of a quintet. I do wish the book was longer and a little more detailed but that would be my only issue. It most certainly is a hidden gem and a book that I think everyone should read at least once. Also: I can't help staring at this cover!
Recommendation: Read this. Doesn't matter how old you are or what you are into, I think you should read this at least once. It needs to be experienced.
