Elsewhere, by Gabrielle Zevin

When 15 year-old Liz is killed by a taxi cab, she embarks on a voyage to Elsewhere - the place we all go after we die. Here, she learns how to speak Canine, discovers an avocation, makes friends and discovers that life does go on (even when you are no longer alive!), and that there are lessons to be learned in the Beyond.

I would not have considered a novel about the Afterlife to be of much interest to YAs, but if there ever was a YA-appropriate story about life after death, this would be it! With the lyricism of What Dreams May Come and the absurdity of Hitchhiker's Guide to the Galaxy, this is a fairly original vision. It is not, however, of even quality and the last 80 pages of the book really fall apart. A good idea, but flawed delivery.
