Ms. Diana Wynn Jones wrote this fantastical tale and later Studio Gibli turned them into classics. If you love stories of magic gone awry then this book was written just for you.
The title character Wizard Howl is a strange fellow in a world full of the strange and fantastical. The author paints a vivid and fully developed world. She people this world with folks that you know and have passed on the streets of your hometown. Doors lead to new and exciting places. I urge you to give it a try.

This is one of the rare examples of a book-turned-movie that I really like both versions of.
