So when a handsom warrior barges in with news of her father's dying wish - that she marry this stranger on the spot - Moira knows that duty has her bound. Soon Moira realizes the folly of her haste: that her father sent no such message: that she has just exchanged vows with her clan's own enemy, Ian Cameron of Glencoe. Left behind at the convent she discovers she carries his child. But all is not bleak in the foggy Scottish moors: Ian returns to take his bride home, leaving rumors that her life is in danger - but is it from her father or someone else? Ian recognizes in himself feelings he thought he'd never feel again. And although she, too, thinks herself impervious to the emotions of love, Moira may well be in for a surprise.
