The fourth novel in the Cal Leandros series which began with Nightlife, this is clever and hugely entertaining urban fantasy Cal and his half-brother Niko's investigative agency has been managing to stay afloat, but just barely - so when the vampire Seamus comes looking for help to find out more about the mysterious group that's been tailing him, Cal and Niko are happy to oblige. But they're just starting to make progress when Seamus turns up dead. Meanwhile, the inhuman side of Cal's family is not at all pleased with him - killing most of their race and thwarting their recent plan for world domination might have something to do with it. They've vowed revenge, and nothing will stop them extracting their pound of flesh from Cal, starting with his friends. As Cal and Niko struggle to discover who killed Seamus, they must also contend with the vampire Promise's beautiful daughter - and all the trouble she brings in her wake - and stay one step ahead of Cal's bloodthirsty relatives . . .
