When killing people is your job, there's no such thing as a vacation. Then again, how often does an assassin live long enough to enjoy her retirement? In this line of work, you either get lucky or you get dead. And since I destroyed my nemesis Mab Monroe a few weeks ago, all of Ashland's lowlifes are gunning to make a name for themselves by taking out the lethal Spider--me, Gin Blanco. So I'm leaving behind my beloved barbecue joint and heading south with my baby sister, Bria, to cool my heels in a swanky beach town. Call it a weekend of fun in the sun. But when a powerful vampire with deadly elemental magic threatens an old friend of Bria's, it looks like I'll have to dig my silverstone knives out of my suitcase after all. Complicating matters further is the reappearance of Detective Donovan Caine, my old lover. But Donovan is the least of my problems. Because this time, the danger is hot on my trail, and not even my elemental Ice and Stone magic may be enough to save me from getting buried in the sand--permanently.
