Synopsis
The second book in the internationally bestselling Night Watch series—the powers of Darkness and the forces of Light grow closer to war.
For the past one thousand years, the two factions of the Others—an ancient race of magicians, shape-shifters, vampires, and other supernatural beings—have been locked in an uneasy truce as the powers of Darkness and the forces of Light secretly maneuver for the upper hand.
Now in the thrilling follow-up to the internationally bestselling Night Watch, we track members of the Dark Others—called the Day Watch and tasked with keeping the Light Others in check—including a young witch who has had the tragic misfortune of falling in love with a Light Other; a powerful warlock struggling to understand his purpose in the war; and a top lieutenant who worries that Zabulon, the leader of the Day Watch, is planning to betray him. Meanwhile, a forbidden artifact with the ability to bring the most dangerous Dark magician in history back to life has gone missing.
As the inevitable war between the forces of Darkness and Light threatens to destroy modern-day Moscow, it becomes clear that good and evil are only a matter of perspective.
The first book Night Watch is also currently available for $1.99

Synopsis
They are the "Others," an ancient race of supernatural beings—magicians, shape-shifters, vampires, and healers—who live among us. Human born, they must choose a side to swear allegiance to—the Dark or the Light—when they come of age.
For a millennium, these opponents have coexisted in an uneasy peace, enforced by defenders like the Night Watch, forces of the Light who guard against the Dark. But prophecy decrees that one supreme "Other" will arise to spark a cataclysmic war.
Anton Gorodetsky, an untested mid-level Light magician with the Night Watch, discovers a cursed young woman—an Other of tremendous potential unallied with either side—who can shift the balance of power. With the battle lines between Light and Dark drawn, the magician must move carefully, for one wrong step could mean the beginning of annihilation.
