Then May falls into the lake.

When she crawls out, May finds herself in a world that most certainly does not feel like a fuzzy mitten. In fact it is a place few living people have ever seen. Here, towns glow blue beneath zipping stars and the people -- people? -- walk through walls. Here the Book of the Dead holds the answers to everything in the universe. And here, if May is discovered, the horrifyingly evil Bo Cleevil will turn her into nothing.

May Bird must get out.

Fast.
