You could be sitting next to a witch and never know it. They look just like ordinary women but they're extremely dangerous to children! Luckily for the boy in this story, his grandmother knows what signs to look for buy, even so, things don't go quite as planned.

I loved this book when I was a kid, and can't wait to read it again. I remember how scary it was when the witches revealed themselves at the hotel conference. It'll be really interesting to see if it's still as frightening as an adult.
