Rational scientist Eibhlin Fitzgerald tries to relegate the seven-foot-tall warrior to her imagination, but with his flowing black hair, his black eyes alternately burning with desire and flashing with humor, he becomes more real to her than her cheating ex-husband.

Warrior horseman Brandubh mac Dougal vows no other woman will fill the emptiness of his life but the tall, lushly beautiful woman who vanished from his sight as he reached for her.

Crossing a millennium, she falls into Brandubh's arms. Then she must decide whether to return to her own time or to remain with him, to be his lady.
