Caine Black Knife is the third book in Matthew Stover's exceptional Acts of Caine series, following Heroes Die and Blade of Tyshalle. The premise of the series is that a couple hundred years in the future, earth's primary entertainment is the ultimate in reality programming: people live and experience the exploits of "actors" who are transferred to another dimension that is, essentially, your standard fantasy world. Caine was an immensely popular actor, smart and violent; the first two books dealt with one of his Adventures and its fallout on both worlds.
Caine Black Knife picks up several years later, and treats us to two intertwined stories: Now, Caine is older, maybe a bit wiser, maybe a bit more mellow, but no less intelligent and no less dangerous. As he ends up involved in danger and intrigues in new settings, we flash back to the Adventure that made him a star: we see a younger, more narcissistic, self-absorbed and violent Caine making a name for himself, setting the stage for events to come. Caine runs into some characters we've met before and plenty of new ones, comes up against new threats from two worlds and makes a few new friends along the way. It's fascinating to see this character at two very different stages of his life, unmistakably himself in each, yet incredibly different in outlook, in the choices he makes.
Matthew Stover is a great writer of intelligent, exciting fiction that refuses to be confined to a single genre, stories that engage your imagination and make you think even as they provide nearly non-stop action, and make no mistake: Stover's action sequences are nonpareil, brutal and detailed without losing coherence or energy. Every book in this series is fresh and new; Stover never settles for offering just more of the same, and Caine Black Knife stands proudly by its predecessors as a great novel and part of one of the finest sff series on shelves today.
