Adam Black has piqued my curiosity in the previous Highlander books: A larger than life Fae, a Tuatha De, arrogant, sparkly beautiful, seductive, unpredictable, sexual, a player, Queen's consort. A manipulative, totally dark in soul and his thinking male. 
 He loves playing with the humans' lives, plotting and pretending being God. 
 Gabrielle "Gabby" O'Callaghan is a Sidhe-seer and she has the ability to see both worlds; mortal and faery (once again I wish I had read this series before Fever...). 
 Gabby is trying very hard to live a normal life. She is a law student working for a law company that she hates. She also pretends that she does not see fairies. This is something that her grandmother taught her...because fairies are manipulative, soulless, and incapable of feeling anything. They are bad bad beings. 
 It does not matter that Gabby since she was a kid loved them and was fantasizing that a fae prince would come and sweep her off her feet. Her grandmother was strict "Avoid them with any cost. When they find out about you, RUN!" 
 And then Gabby meets the worst of them all. 
 Adam's life collides with her life, when she lifts her eyes and sees him and her glance stays there. She does not pretend that she does not see him or that he is transparent and she is looking something behind him. She cannot take her eyes from him. And then she RUNS. And he RUNS after her. Of course she will be caught LOL 
 Trying to survive a terrible curse, Adam will use Gabby. They will travel from USA to Scotland, attempting to avoid other fairies and Hunters and not be killed in the process. Our favorite highlanders and druids Drustan and Dageus will help. 
 In the end Adam has to make decisions. How far can he go? How many things he can sacrifice for Gabby? How can he fall in love, when he is not supposed to feel anything. 
 This is by far my favorite book in the series. Adam is definitely my favorite character.
