Alice/Spok in Wonderland

I've read a lot of books based on Alice in Wonderland and I consider this one to be one of the absolute worst of them all.

It fails on several levels. First, there's a lot, and I mean a lot. of bad language. There's a lot of violence. Finally, the story (at least to me) seems to be quite racist, using the most negative stereotypical 'black language' possible.

Did I mention the decapitated heads that were planted, grew into vines with heads which were then harvested and eaten?

A disgusting book in every way I can think of.
