Evil has moved into the sleepy little town of Crater Lake, Iowa. A serial killer is murdering young girls and it’s Sheriff Nathan Murphy’s job to stop him. But there’s nothing cut-and-dried about this investigation. The killer drains his victims’ blood before staking them through the heart and decapitating them. Nathan enlists the help of an FBI Profiler, Lindsay Trujillo, to aid in the investigation of these heinous crimes, and things take a supernatural turn when they discover they might not be dealing with something human at all, but something much older and much more dangerous. Why are some of the victims wearing masks that represent the Unknown Girl of the Seine? Are they dealing with a serial killer or a vampire? Or both? Whichever it is, Nathan knows one thing for certain: they are looking for a monster.

Lindsay Trujillo Returns . . . After a paranormal encounter on her last case, Special Agent Lindsay Trujillo has placed herself on an extended leave of absence from the FBI’s Behavioral Analysis Unit as she tries to cope with the events of the past. But Lindsay knows better than anyone that evil never rests, and now a new serial killer is on the loose, crossing the country while he leaves a trail of bodies in his wake. To Fight Another Monster . . . There seems to be no apparent rhyme or reason to the murders, but the killer leaves the same disturbing signature, one too specific to be deemed a coincidence. The UNSUB also collects a unique and interesting trophy from each of his victims. Lindsay knows if she can determine the why it will lead her to the killer. But these days she has demons of her own to contend with. Demons that have forever altered her perception of reality and left her doubting her abilities as an agent. Can She Conquer Her Demons . . . Can she set these issues aside in order to track down a madman? Even more terrifying, Lindsay suspects the more she gets involved with the case, the more likely it will land her smack dab in the center of the supernatural again.
