Nika, the pack’s newest scout, wants nothing more than to please his Alpha. When he discovers a beautiful, and very sick, stranger in the woods outside Los Lobos, he finds himself torn between his duty and his hormones. The stranger carries a deadly wolf virus—one that hasn’t been seen in the Black Hills in ages. Kimi, a Lakota Sioux, is dying. She’s transported herself forward in time, hoping to find the cure to the illness that’s stricken her tribe. Her only chance for survival is to trust Nika, even if she’s not used to having help. To find the cure and save the pack, Nika and Kimi must travel to a time long ago—before the Lakota populated the Black Hills—a time filled with dangers neither can imagine. Their growing attraction may save them, or kill them both.
