I recently finished Dangerous Highlander by Donna Grant, the first novel in her Dark Sword series. The book was published in paperback by St. Martin's Press in 2010.
I don't usually give five stars to romance novels (though I am a big fan of them), but this one earned my respect early on. By chapter three I was completely hooked on this series. The three MacLeod brothers--eldest Fallon, middle brother Lucan, and youngest Quinn--are simply irresistible.
It's not just that they're gorgeous Scottish Highlanders, either. Thanks to the workings of ancient Druid magic, originally used to fend off the Romans, the three brothers share an ancient god trapped inside them. A madwoman seeks to capture them because of this, and because of their secret, their clan was slaughtered. For three hundred years, the immortal brothers lived alone in the ruins of their castle with only their vengeful god for company. When an innocent young nun-in-training, Cara, ventures near their forbidden hold, she senses there's something magical about the place, but she never expects to fall in love with one of the brothers. This book was the perfect blend of romance and sword and sorcery, with moments of action but also a great heart, great chemistry, and an unforgettable band of brothers.
I took Donna Grant's Dark Sword quiz on FaceBook, and the quiz suggested "my" brother is Fallon. Okay, so Fallon does slightly resemble my husband, but so far I think I like Quinn a little better. I won't really know until I get my hands on the next book in the series, Forbidden Highlander. I plan to do that on my next trip to the bookstore.
