A Cold Day In Hell

Five college freshman, each with a supernatural past they'd rather forget, have to work together to solve the murder of a stubborn ghost and keep their university from going to Hell. Literally.
Heather once made a deal with the Devil, and was lucky to get out of it with her soul intact. Now she just wants to be a normal college kid. But her roommate is possessed and killed by a demon on her very first day.
Donovan is a necromancer who no longer wants anything to do with ghosts. But this one ghost girl insists her murder is part of something bigger, and won't take no for an answer.
When a cursed immortal offers to hire them to help solve the mystery, heather and Donovan can't refuse. As more demonic activity plagues the university, they must work with a knife-wielding demon expert, a supernatural tech genius, and a girl who cheated death itself to figure out what is stirring from beyond the grave. In order to free the ghost's soul and save their university, Heather will have to make one more deal with the Devil, Donovan will have to embrace his true powers over the dead ... and someone on their team will have to die.
