Mongrel Trilogy

One day a shadow is cast on the Mechanical Circus, a rollicking seaside carnival where imagination meets machinery, when a tall, cloaked figure approaches the stand of Will Marchman, a young patent-medicine salesman. Thus begins the adventures of Will; Fanule Perfidor, commonly known as the Dog King; vampire Clancy Marrowbone; and Clancy's former lover, the mortal Simon Bentcross.
