"Britt Pheiffer has trained to backpack the Teton Range, but she isn't prepared when her ex-boyfriend, who still haunts her every thought, wants to join her. Before Britt can explore her feelings for Calvin, an unexpected blizzard forces her to seek shelter in a remote cabin, accepting the hospitality of its two very handsome occupants;but these men are fugitives, and they take her hostage.

Britt is forced to guide the men off the mountain, and knows she must stay alive long enough for Calvin to find her. The task is made even more complicated when Britt finds chilling evidence of a series of murders that have taken place there and in uncovering this, she may become the killer's next target.

But nothing is as it seems, and everyone is keeping secrets, including Mason, one of her kidnappers. His kindness is confusing Britt. Is he an enemy? Or an ally?"

Becca Fitzpatrick is a New York Times bestselling author. Even if she has plenty of books she is so successful. She has written 5 books, one of them is Black Ice and the other are in Hush Hush series that includes 4 books. Hush Hush series were also brilliant that I've read every single of them 3 times. It's about  nephilims and fallen angels. I suggest you to read it too!
