Dorothy and the Wizard in Oz

Dorothy is in Oz again, this time as a result of an earthquake. She meets back up with the Wizard and she comes across the Mangabooks, vegetable people; the Braided Man; and land of the Gargoyles, where everything is made of wood. The characters she meets on her road to finding her way home, as always, are the charm of this series.

These stories get darker and darker. They also make less and less sense. I think I'm giving up on these books and going to Wikipedia to sum up the rest.
