The Replacement (Twins #11)

Twins like Eric Kincaide and his sister, Naomi, know each other's every thought. But that closeness came between him and Lindsey Nelson, the woman he'd planned to marry, four years ago. When their wedding plans fell through, Lindsey ran as far and fast as she could.

Now Eric heads a small team of winter rangers in Yosemite, a team that includes his twin sister. They're looking for a kidnapped child hidden somewhere in these snowy mountains. When one of his rangers dies in an avalanche, he needs a replacement, someone who specializes in handling search-and-rescue dogs. That someone is Lindsey Nelson.

The hunt for a missing child brings her back to snowbound Yosemite, back to a place she wanted to forget. Back to a man she can't forget - and the twin she can't forgive.
