Having left most of his arm and his self-confidence behind in the Afghanistan desert, young veteran Aaron Santori has enough on his plate learning to use his prosthetic arm. Attending graduate school at the University of Pittsburgh makes life both interesting and challenging. Mentally, he's ill prepared for meeting Rhys Edwards, a young-adult novelist from Wales and everything Aaron could want in a man. Between the scars from the explosion and his PTSD, he’s reluctant to date. Ready or not, though, Aaron finds himself jumping into the deep end of the relationship waters. What Aaron couldn’t possibly know is that Rhys isn’t human at all. As a prince of the Tylwyth Teg, Rhys is fae, with a list of enemies he’s accumulated over the past few centuries—among them a former lover, Morcant, who is back to make Rhys’s life miserable. An unwitting pawn in their Machiavellian fae politics, Aaron only knows he’s falling in love, never suspecting love might be his death sentence.
