Gaelic Magic

When romance author Delu Morris is troubled with unexplained panic attacks, she seeks help from a doctor who's researching dream-therapy. He explains that he'll accompany her into her dreams to revisit her memories and to try to uncover if an event from her past is causing her trouble now. His grad assistant is a handsome Scotsman who wears a kilt the first time he meets her. She's intrigued, but they remain at arms' distance while he's a part of her therapy team.
When she discovers that only he can make the machine work, he confesses that he's the 7th son of a 7th son, and the Unseelie are using him for some unknown reason. When he touches the controls, he pushes a wee bit o' magic into the machine to make it work. Will they discover together what her long-lost memory is? Or will the guilty person manage to keep her from that discovery-for good?
