When vampire hunter Laura Caxton is locked up in a maximum-security prison, the cop-turned-con finds herself surrounded by murderers and death-row inmates. But soon she learns that an even greater threat--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. The crafty old vampire knows just how to pull Caxton's strings, and she's issued an ultimatum that Laura can't refuse.
