There's something wrong with Charles Wallace. He gets tired too easily, he looks pale, and he is being severely bullied at school. Meg is terribly worried about him. So is their mother, even if she doesn't want to admit it. Just then, they meet The Teacher. Turns out, there IS something really wrong inside Charles Wallace and his life and the whole universe depend on them finding the solution.
I did like this book, but I only gave it 3 stars because it felt like a "chapter" in a book, more than a book on itself. I found it entertaining and lovely, but I kept expecting something else to happen. I do love the characters and I will definitively continue with the series!
[I'm counting this one for the 2014 TBR PILE CHALLENGE]
