The assassin Shadrak the Unseen is down on his luck. He’d have to be to take a job from a wizard. To make matters worse, the ring he’s commissioned to procure is stolen by an invisible thief, whose footprints lead to the city of New Londdyr—where Shadrak is still wanted for an ages-old crime. Soon enough, he learns that rival wizards will do anything to possess the ring, despite the sinister rumors that surround its creation.
