Northern Heat by Jerry Cole

The Department of Preservation of Natural Resources in the State of Alaska could never find the ideal person to spend entire winters alone on one of their northern-most islands until they found Trevor. Trevor is a reclusive grouch with a shady past who is all too eager to spend his winters completely alone on the tundra. That is, until he comes across a mysterious man named Christian lying injured in the wilderness.
Christian doesn’t remember how he had gotten on the hard to access island or, if he does, he’s not telling. Trevor feels a certain magnetism toward the other man that conflicts with the sense of unease from sharing a desolate island and a small cabin with this total stranger with a mysterious past. Then again, Trevor’s not one to talk when his past includes intrigue from the upper echelons of Manhattan, an obsessed former fiancée, and an attempted murder.
Will Trevor be able to learn more about this mystery man? Will he be able to overcome his growing attraction to him? Most of all, will he be able to overcome his dramatic past and learn to trust again?
