The Nightwatch

The book is split into three separate stories. Plots and counter-plots abound as he tries to be more than a pawn in the game being played between the two sides.
Anton is a good character and the book is written in the first person from his perspective. It's an interesting view of Russia with vampires, werewolves, shape-changers and magicians.
Quite introspective, possibly due to it's Russian origins, raising questions about who decides what is good/Light or bad/Dark.
