In the next 23 hours, there will be no reprieve, no mercy, and no time off for good behavior.When vampire hunter Laura Caxton is locked up in a maximum-security prison, the cop-turned-con finds herself surrounded by countless murderers and death-row inmates with nothing to lose . . . and plenty of time to kill. Caxton�s always been able to watch her own back�even when it�s against a cell-block wall�but soon she learns that an even greater threat has slithered behind the bars to join her. Justinia Malvern, the world�s oldest living vampire, has taken up residence, and her strength grows by the moment as she raids the inmate population like an open bar with an all-you-can-drink supply of fresh blood. The crafty old vampire knows just how to pull Caxton�s strings, too, and she's issued an ultimatum that Laura can�t refuse. Now Laura has just 23 hours to fight her way through a gauntlet of vampires, cons, and killers . . . 23 hours to make one last, desperate attempt at protecting the world from Justinia�s evil.
