Ten books and over 2000+ pages of magic and mayhem, action and humor fill this snarky urban fantasy boxed set. Mythical creatures are real, and the world is just finding out. Discovering that your neighbor was once an evil, blood-sucking fiend tends to bring property values down. Katrina Darling’s only real friend has been murdered. And not just murdered—ritually sacrificed by a serial killer. Kat is sure more death will follow. She should know … she used to be the monster plunging the blade in. Trouble is, after three hundred years of being a vampire, Kat has forgotten what it means to be human. One thing she does remember is that friends matter. Now she's determined to find whoever—or whatever—killed her friend before more victims surface. But just as the hunt begins, a mysterious young man discovers exactly what she was. Kat has a decision to make: Run and keep her monstrous past hidden, or avenge her friend and save the city from a merciless serial killer.
