Author Ryan Turner, accompanied by his cat, Constable, has just moved into the house he inherited from his aunt. Unfortunately the original owner, Adrian Devoe, also lives there. However, Ryan is unaware of this since Adrian is a vampire. Deciding there is nothing he can do to oust Ryan, Adrian, pretending to be a human with an allergy to sunlight, manages to wrangle an invitation from Ryan to become his housemate.
The two men become friends and slowly realize they are drawn to each other. Then Adrian's great-uncle, the vampire who turned him, appears to warn Adrian that Darnell--a vampire who almost killed Adrian during the Civil War--has reappeared, intending to finish the job.
The question then becomes, will Adrian be able to keep Ryan and himself safe when Darnell shows up? And if he can, will Ryan be able to accept that the man he has fallen in love with is a vampire and his great-grandfather--although not by blood?
