Frankie Latimer and her best friend, Adelaine Harper, were two former vampire hunters until they were turned by a rogue vampire in a rusty junkyard. Of course, that was three months ago. Now, the two are on a "No Heartbeat Diet", only drinking from the blood bags they take from hospitals(torturing themselves with the guilt of killing the humans they had been protecting was too much) and the blood of a select few animals. Frankie and Adelaine also continued to not only kill the nasty bloodsuckers that destroyed their lives, but kill any supernatural being that threatens the lives of the humans they used to be. But what happens when on a mission, they meet hunters Sam and Dean? Will they die, or will they work together to slay monsters as a team?
