Bed-Knob and Broomstick, by Mary Norton, is about three kids who have an awesome adventure on a flying bed. They move to a town to live with their aunt. In this town, they discover that one of the women is a witch in training. She gives them a magic bed that can fly so that they don't snitch that she is training to be a witch.
There is also a movie about this book that is very similar. One difference is that in the book, they fly on the bed to an island that turns out to be populated by cannibals. They barely get away with the flesh on their bones. In the movie, they go to an island, but instead of there being cannibals, there are animals.
I'd recommend this book to people who like witches, wizards, magic, and that sort of stuff. It wasn't my favorite book because it was sort of dry, not really juicy. It has excitement, but it didn't excite me too much. There wasn't enough action in it for me.
This is a really good book, just not for me.
