The Hollow Chocolate Bunnies of the Apocalypse by Robert Rankin.. it's on the funny side, and reminds me of the comic series Fables, Roger Rabbit, and that whole fractured Fairy Tale kind of thing.... so far it's fun and slightly silly...
Back of the book:
A boy named Jack sets out to seek his fortune in the big city, but when he finally gets there, it is Toy City, formerly known as Toy Town. There is a serial killer loose upon the streets. One by one, the old, rich nursery rhyme characters are being brutally slaughtered. The Toy City police are getting nowhere. Bill Winkie, Private Eye, has also mysteriously vanished, leaving only his sidekick, Eddie Bear, to take care of business. But Eddie is ready, and when he teams up with Jack, the two set out on an epic adventure, not to mention a lot of heavy drinking, bad behavior, fast car chases, gratuitous sex and violence, bizarre toy fetishism and all-round grossness of a type not normally associated with Toy Town.
