The Danger with Sinners - Sinners, #3

An ancient vampire, Tacha, stands accused of using her company, Research Inc., as a cover for the development of a weapon of mass destruction-- the ultimate vampire. Caleb, aka Danger, has been sent to infiltrate the home of the Sr. V. P. Narmer Horus in hopes of uncovering clues to Tacha's whereabouts. Disguised as head of security, Danger finds his biggest challenge isn't the man he's investigating, but the man's headstrong daughter, Kim. However, just as Danger isn't what he appears to be, neither is Kim.
