Unidentified floating objects over the U.S.A. force the Holt Agency and Black Swan Team 2 into the frozen Alaskan winter.

Kenner Lane grew up struggling in the unforgiving Alaskan interior. He knew what it meant to be freezing cold and how to avoid it. Move away. Joining the Navy the day after high school graduation was step one. Becoming a SEAL was step two. Subzero temperatures for months had been all the motivation he'd needed to earn his Trident. Now medically retired and a Holt Agency employee, he went where they paid him to go. Even if that meant guiding a bunch of women through his godforsaken birth state.

Lieutenant Piper Knight always expected the best of herself. She would have made the Olympic swim team but instead took a commission in the United States Navy. She'd been accused of being half fish because of her love of all things water related; swimming, snorkeling, SCUBA diving, even fishing. Completing the Joint All-Female Special Operations School at the top and joining Black Swan Team 2 accomplished her next goals. However, she had never aspired to go to Alaska in the dead of winter, hunting what might be nothing more than a high school science experiment gone wrong.

Opposites can attract but can Piper get Kenner past his preconceived notions of women and his loathing of the cold and allow her to warm his heart?
