Owner of the wildest, loneliest ranch this side of the Rockies, Luck MacKenzie hadn’t laid eyes on Carla McQueen for three years. Not since they day he’d sent his best friend’s kid sister storming from the Rocking M Ranch and out of his life - for what he thought was forever…

    Now Carla was back, lovelier and even more desirable than in his burning memories. But Luke knew he could never give in to the raging need to make her his woman. For he’d made a vow long ago - one that he was determined to keep - that he would never fall in love with Carla McQueen. No matter how badly his body and soul ached for her…

Returning to her sprawling Colorado ranch with nothing but her battered car and a treasure map, Mariah MacKenzie encounters prospecting partner Cash McQueen, an argumentative, burly type who becomes all too aware of Mariah's innocence.

Janna Wayland, the wild stallion Lucifer, and Ty MacKenzie, the stranger who had come for the stallion but stays to capture Janna's heart, join forces to escape from the steep mountains and canyons of the Utah Territory, where El Cascabel and his renegade warriors roam.

When wildlife biologist Eden Summers arrives in the Colorado Rockies, she has only one thing on her mind: to continue her research on the local cougar population. A capable woman, used to living and working alone in the wild, she is self-possessed and confident, able to handle any threat from nature's fiercest predators -- until she gazes into the eyes of Nevada Blackthorn.

She pulled him, injured and bleeding, to safety in the middle of a storm, unleashing a man who would invade her deepest dreams. But Nevada -- a rancher by trade, a warrior by nature -- is a man who has learned that walking away from caring is the only key to survival and that only the strongest survive. Any woman fool enough to try and change him will be hurt -- badly -- for their efforts.

Perhaps Eden is that kind of fool. Or perhaps she has no choice but to follow a calling as fierce, as wild and as natural as the beating of her own heart . . .

    Could she let go of the past long enough to imagine the future?

    Diana Saxton is planning to spend the summer alone, uncovering the native artifacts that are her passion-the only thing that has helped her survive a past that she would rather forget. But experience has taught Diana that the security of her academic world can shatter as easily as the delicate relics she collects.

    Now, her love for history has brought her to the magical Colorado landscape. As an anthropologist, Diana's thrilled by the chance to discover the secrets of September Canyon. Then the solitude of her trip is jeopardized by a stranger as tough and commanding as the land itself. Tennessee Blackthorn knows that the shy professor doesn't welcome his company, but he's promised to watch over her safety.

    Diana's never trusted anyone to share her world before. Now she's alone with a stranger, in a place where nature holds the history of the land. And suddenly, Diana is discovering more than the past. She's finding her future…
