Black Bird by Logan Fox

Chemistry professor, Jason Lorye, needs a place to heal his broken heart, and Mallhaven University seems the perfect fit. In his first week, he witnesses so many inexplicable things that he starts investigating the University's past. When Samantha Smith meets the new chemistry professor, she knows he's perfect for her. Although he's receptive to her charms, she has no idea what he'd think if he knew about her secret. Jason soon discovers what's happening in Mallhaven's licentious underbelly. The truth rocks him to his core, especially when he discovers the woman he's falling for is involved in it. If Jason leaves, he'll lose Samantha. If he stays, he may lose himself.
