Long before Buffy showed the world how tough girls could be, Mercedes Lackey created Diana Tregarde. Diana is a Guardian charged with saving innocents and destroying evil wherever she finds it. Because if she doesn't, evil will find her-and kill her first. In Children of the Night, Diana is running her friend's occult shop in New York City when trouble does finds her. Mr. Trouble, as she calls him, is a vampire whose psychic power makes her radar go off the charts. So when she discovers that he's the new benefactor of ex-boyfriend Dave Kendall's band, she's not surprised to see how bad Kendall looks. It will take all of Diana's power-and the aid of a sexy vampire protector with a score of his own to settle-if she's to save Kendall now.... In Burning Water, Diana gets a call from Detective Mark Valdez, an old college friend turned cop.
