Day Watch

Used The second in a series of novels, Day Watch brings us back into the world of Sergei Lukyanenko and continues the dramatic battle between good and evil, light and dark, day and night.
Set in a modern-day Moscow, the 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 Dark - The Day Watch - keep an eye during the day, the agents of Light keep watch over the nights. For a thousand years a treaty between the years. Two sides have maintained an uneasy balance, but when a very potent artifact is stolen from the Inquisition - an impartial group of Others who keep watch over all - the consequences are dire for both sides.
Day Watch introduces the perspective of the Dark Ones, as it is told in part by a beautiful but troubled young witch. When she falls in love with a handsome young Light One, the balance is threatened and a death must be avenged.
