Nightshade Series by Lora Leigh, Michelle Rowen, Jory Strong, Ava Gray

Jillian Conrad never believed in vampires-until she was unwillingly injected with a serum that was supposed to act as a deadly poison to them. Now, tormented half-vampire Declan Reese wants her blood to destroy the undead kingdom. Unfortunately, the serum has also made her blood irresistible to all vampires-including Declan, whose desire for Jillian is more than mere hunger.

Four all-new stories of primitive desire- with a never-before- published novella of the Breeds. #1 New York Times bestselling author Lora Leigh returns to her sensual world of the Breeds in an all-new novella that explores just how savage, and how far, a man is willing to go in the name of desire. Plus three other stories of irresistible passions from three masters of hot paranormal romance.

Jillian Conrad's blood has killed the vampire king. Now an enemy to all vampires, she is targeted for elimination. So is the infant daughter of the dead king. If Jillian doesn't stand in the way of her death, then everyone, living or dead, is in great peril.
