The Immortal Highlander by Karen Marie Moning (2005, Paperback, Reprint)

I've read, and own, every one of Moning's books, and can't wait for the next one, but this is my favorite. I'm sorry that Adam Black won't be around to make his mischief in Moning's future books. He was quite a character. But this is the love story to end all love stories. Being Fae he's everything Gabby's heard about him. He's arrogant,lethally sexy and downright dangerous. But he's also charming, funny and terribly romantic and won't give her a minutes peace. They have their fun and their frights as they flee the evil unseelie hunters. They do get help from some Druid friends you might remember from previous books. But in the end, with the help of the Fairy Queen, Adam wins his lady love and they do live happily ever after.
