House of Many Ways

I loved it just because it I never saw this type of book geared towards kids where you're supposed to cheer for these people. It's so different from what you're used to getting like a very straightforward story. The second one I thought was really fun to the third I don't remember liking as much but I guess I'll have to go through the two of them again house of many ways is the third one and oh castle in the sky is the second one which is a take on the Arabian Nights stories.
