Charlie is a liar. He meets the Skull of Truth and is cursed to always tell the truth, and his life changes in unexpected ways. Telling the truth gets him into a lot of trouble, and the curse begins to affect other people around him.

I didn't enjoy this book as much as some of the others in the Magic Shop series. I thought some of the plot points didn't quite fit in with the rest of the story. There were some radical leftist political ideas that I didn't agree with. I was surprised to find them in a children's book.

I was pleased to find that the skull himself is not scary at all. He's a humorous and silly character, and there's nothing frightening or creepy about him other than the fact that he's a skull.

There are some funny bits of dialogue, and some interesting character development. The plot is all over the place though, and I didn't really connect with any of the characters.
It's a good story, but not amazing.
