Night Watch

Others. They walk among us, observing. Set in contemporary Moscow, where shape shifters, vampires, and street-sorcerers linger in the shadows, Night Watch is the first book of the hyper-imaginative fantasy trilogy from bestselling Russian author Sergei Lukyanenko. This epic saga chronicles the eternal war of the "Others," an ancient race of humans with supernatural powers who must swear allegiance to either the Dark or the Light.
The agents of Light - the Night Watch - oversee nocturnal activity, while the agents of Dark keep watch over the day. For a thousand years both sides have maintained a precarious balance of power, but an ancient prophecy has decreed that a supreme Other will one day emerge, threatening to tip the scales. Now, that day has arrived. When a mid-level Night Watch agent named Anton stumbles upon a cursed young woman - an uninitiated Other with magnificent potential - both sides prepare for a battle that could lay waste to the entire city, possibly the world.
