Query: This is a damn good.

This is a damn good book. It gets off to a slow start start, but even then, it is still a really good book, and i would recommend that anybody read it. He author seems to spend about the first half warming the charecters up, but then in the second half, it goes weird, every page theres something to laugh at.Go read it.
