When Abigail Collins heard Nick's theory on their current case, she knew he had to be crazy, but when a zombie shows up in her apartment she has no choice but to believe him. A renegade necromancer bent on manipulating witches and murdering innocent people runs amok in town and Abby and Nick have to stop them before more bodies pile up. Further complicating matters, two PIB agents step onto the scene, claiming a link between their case and Abby's. To top it all off, blood-starved vampires are causing chaos in the city. It's just another day for PIB Agent Abigail Collins, full of blood, monsters, and explosions.
