Beka Cooper has completed her training and is now an official Dog. It has been a tough summer-Beka is having trouble keeping a partner, and the poor harvests have brought unrest to the lower city. When Beka's friend Tansy brings word that false silver coins are appearing in the city's markets, Beka and the Dogs of Jane Street Kennel investigate. The trail leads to a gambling ring, recently arrived in Corus from Port Caynn. The hunt must be kept secret, for if word gets out the economy will be in chaos. Already, bread prices have skyrocketed, sparking a riot in the city's Nightmarket. When Beka runs foul of a nobleman's son, she and Goodwin are sent to Port Caynn to investigate the false silver coins. The counterfeiters could be anyone, including friends, and even lovers. Beka must keep her senses sharp if she wants to catch her prey.
