The Immortal Highlander (Highlander 6)

BEWARE:
LETHALLY SEDUCTIVE ALPHA MALE OF IMMENSE STRENGTH AND DARK EROTICISM. DO NOT LOOK AT HIM. DO NOT TOUCH HIM. DO NOT BE TEMPTED. DO NOT BE SEDUCED....

With his long, black hair and dark, mesmerising eyes, Adam Black is Trouble with a capital T. Immortal, arrogant, and intensly sensual, he is free to roam across time and continents in pursuit of his insatiable desires. That is, until a curse strips him of his immortality and makes him invisible, a cruel fate for so irresistible a man. Now Adam's only hope for survival is in the hands of the one woman who can actually see him.

Enter law student Gabrielle O'Callaghan. For Gabrielle, cursed with the ability to see both worlds, Mortal and Faery, it is the beginning of a long, dangerous seduction. But as Adam's quest to regain his immortality plunges them into a world of timeless magic, the price of surrender could be their very lives. Unless they can thwart the cosnpiracy that threatens both Mortal and Faery realms...and give them a shot at a destiny few mortals ever know: glorious, wondrous, endless love...
