While helping a wounded half-troll assassin escape the service of Raven, the vampire lord ruling the city, Magpie and Jynx find themselves embroiled in a plot devised by his second-in-command, the devious vampire, Tabitha. Hunted and harassed by a mercenary army of trolls and Tabitha's faithful shifter, the group discover that not even Marlon's magic shop can provide a safe refuge from their enemies. With an army of trolls laying siege outside their door and time running out for their poisoned charge, it seems that not even an unexpected ally, previously concealed by the magic blanketing the city's core, will be enough to help them survive the long, deadly night.
