"On that Tuesday mid-afternoon, I remembered looking out the window and watching the snow fall from the top of the clear world, and to the dirty and gritty ground, and I remembered that was the last time I could ever see the beauty in it. 

Oh, how I hate acid snowflakes."

While working on homework in a small café in Loveland, CO during her holiday-break, a man comes up to the 15-year-old, Tavi Smith, and starts a conversion. 

That was her first mistake.

When he 'accidentally' spills coffee on her, he runs and buys her a new one. Feeling that Tavi had to be polite, she takes the coffee. 

That was the second mistake.

Believing that he was a trustable, funny, kind man, she takes a drink of her coffee. 

That was her third mistake.

The man ​drugs her, and takes her away, deep in the Rocky Mountains, with the heavy winter snow covering their tracks. Imprisoned in a cabin, far away from her family and friends, it's just her and a strange man named William. He is arrogant, cocky, unpredictable, dangerous . . . but the only person that she has for miles.
