The Night Watch

From Amazon.ca,
In The Night Watch, the first of a trilogy, and reminiscent of Philip Pullman’s His Dark Materials in its ambitions and achievement, the setting is contemporary Moscow. A small number of Muscovites with supernatural powers — those who are Other, owing allegiance either to the Dark or the Light — co-exist in an uneasy truce, each side keeping a close eye on the other’s activities around the city.

Anton, an Other on the side of the Light, is a night-watchman, patrolling the streets and Metro of the city as he protects ordinary people from the vampires of the Dark. On his rounds, Anton comes across a young woman, Svetlana, whom he realizes is under a curse that threatens the entire city, and a boy, Igor, a young Other, as yet unaware of his own enormous power. Partnered by Olga, an Other who is in the form of an owl, he struggles to remove the curse and thereby save the city, while at the same time prevent Igor from falling into the clutches of the Dark.
