Jerzy Arlecki was never the sort to believe in vampires, and he certainly never believed that there might be a special unit of vampires within the military, purely to protect humanity from the blood-thirsty renegades. Through an unfortunate twist of fate, he finds himself awakened to the night the hard way. He takes a vow to stand with the Nighters, on the side of the good and righteous, only to discover that it may be harder to keep his oath than he thought.
Meanwhile, Vesper finds himself wounded and helpless in the clutches of the renegades, abandoned by the Nighters. Life amidst the ranks of his former enemy is challenging, to say the least. To some, he is a traitor and a murderer, yet to others he is a symbol of hope, the unbeatable desperado who dared to assassinate the powerful Lord Ultor.
Rather than let him die of his wounds, the renegades save his life by forcing him to become the one thing he swore he would never be: a full-fledged vampire, dependent on human blood to survive.
With old friends plotting revenge and new friends who may yet become enemies again, Vesper must find some way to navigate the murky waters of his new life. Who can he trust? More importantly, where does the line between righteousness end, and evil begin?
