Jayda works as a paramedic, when she returns after a vacation, a new medic is hired. Ben and Jayda´s first meet is filled with powerstruggle but he soon wins her over.
Soon they realize that they´ve got more than a profession in common.
Ben is a former demon-hunter with powers she´s never heard of, hunting a demon who is after Jayda.
Jayda´s husband manufactured Heaven, a drug with awful repercussions, before he died in the accident that changed Jayda´s own life. Now the drug is back on the scene and Jayda needs to stop it, with Ben´s help.
Action, suspense, PNR, fantasy, smut and demons.
You can tell that Elizabeth Otto works as a medic herself, since the description is spot on re: her work.
