Slipstream by Michael Offutt has a very entertaining concept. Combining Arthurian themes with examples of advanced technology, a society that where the rich buy the life essence of the poor, alternate realities, and spirit animals leads to a book that has a unique feel.
The story that the book tells heavily involves two things that I know almost nothing about hockey and advanced math. Despite those two things being featured I still really enjoyed this book. The characters are done well for the most part though I find the relationship between Kolin and Jordan to be pretty creepy. That being said I also feel the need to put in a disclaimer that there is a pretty intense sexual episode in this book, which is not something I enjoy personally.
I think this is the beginning of a great series and I'll be checking it out further. I've actually already read book II and will be doing a review of that soon as well. This is a great book for scifi fans who are looking for some new twists to the genre.
