Book 1

Vampires. They hunt in every major city, hidden by the crowds, shielded by disbelief. They are Killers, and their prey is human. Not all vampires are Killers. The Guardians of the Night sacrifice the superior physical and psychic strength that comes with feeding on humans to protect them. But the Guardians walk a thin line, for even a single kill could leave them helplessly addicted to murder. When detective-turned-P.I. Carolyn Mathers was left at the altar, she never once thought her fiance had been turned into a vampire. Two years later, Gray reappears, bringing murder, mystery, and an unbelievable tale of Guardians, bloodthirsty Killers, and his own transformation with him. And he's been accused of murder. A first-rate P.I., Carolyn is determined to help. Gray won't allow what he is now to taint her-but Carolyn vows to never let him go again. But will helping Gray mean becoming a creature of the night?

Secrets in the Shadows

by Jenna Black

Published 1 May 2007
The Guardians of the Night: a sect of vampires in Philadelphia who don't believe in drinking human blood, and who have taken it upon themselves to protect the humans in Philadelphia from all bad vampire elements. Now one of their own has gone rogue - and is planning to kill a vampire who's living in Baltimore. Two people are dispatched to find Jules and stop him: Drake, a killer vampire with a killer instinct, and Hannah, a human Pl with an eye for trouble. When humans and vampires mix, things always get complicated. Drake melts into the shadows, but Hannah marches right up to Jules - and her lust for him complicates their situation even more. Jules knows there's no way he can salvage his original plan now - to extract revenge upon his maker for forcing him into an unlife of vampirism - but oddly enough, the more time he spends with Hannah, the less he wants revenge. But is it lust or love? When circumstances force Jules to transform Hannah into a vampire, he thinks that's the end for whatever budding relationship they might have had - but for Hannah, it's the beginning of their eternity together.
