I enjoyed it. Gives some good backstory to Slade, Blood, and Rochev. Also explains (maybe?) why the son seen in LOT is different than the one Slade mentions in S1. What it doesn't explain is where the LOT kid comes from; Slade has to have had a relationship with some woman off-screen either this season or in the next one or two, given the kid's apparent age 30 years from now (as in, mid-20s or right around 30).
Thanks. Maybe the book was written before they came up with that story for LOT, regarding Grant. I expect this book to be enjoyable and a good read, but I most likely will not consider it canon, even if it is supposed to be. I remember there used to be books that came out during Buffy that were supposed to be canon too, but I don't think they were referenced on the show. I doubt this book will be either. Storylines that they come up with in the future may contradict stuff in this book. I would not be surprised if that happened with the Buffy TV show and the books. That doesn't bother me though. As long as it is a good read, I am happy.
