Passion ignites in Antarctica when the only thing keeping an experienced polar guide safe is an intense, enigmatic former Navy SEAL.

Former Navy SEAL and CIA agent Ronin Cooper is used to living his life in the darkness. A loner by nature, he enjoys his work at Treasure Hunter Security, stays busy on the road, and never lets anyone too close. That is until he notices a mysterious redheaded woman spying on him and his colleagues.

Peri Butler will do anything to save her sister. The experienced polar guide knows the deadly black-market antiquities ring, Silk Road, has her twin, but Peri isn't sure who she can trust. She wants to believe Treasure Hunter Security can help, and soon finds herself facing off with the dark, intense, enigmatic Ronin.

Ronin and Peri find themselves headed to the frigid ice and snow of Antarctica on a dangerous rescue mission. Their intense attraction generates scorching heat, and as they work to track down Silk Road and Peri's sister, they are drawn irresistibly closer. But what they find buried in the ice could threaten everything. Ronin will sacrifice it all to protect Peri, while she will take every risk, not only to save her sister, but to break through the protective shell around Ronin's heart.
