*Quick not so formal review*
I read Block's Weetzie Bat a few years ago, and I think that helped prepare me for reading this book. Block has an interesting way with language that is beautiful to read, but can also lead to some minor confusion and rereading. It's not a fault in the writing though. It helps it stand out and allows for the story to do interesting things.
Block takes well known myths and weaves them together into a set of modern day characters. It's often hard to tell where the myth and the "real world" aspects of the story are because of the blending and language used. But there's a beauty to how this story is told. I feel that I'll need to go back and read it again some time down the road to full appreciate it, though. I wasn't until about halfway through that I was able to find the flow through the verse, especially with it's lack of punctuation.
I'd be very interested in reading some other poetry (non verse novel works), after reading this. I'll have to go see if there's any out there.
If you're looking for something different, something that might not "click" right away but will make you think and pay attention, this might be a book to check out.
