"The tension, the atmosphere, the dread . . . This is a book that sticks in your head long after the last page." --Lisa Jewell
"Extraordinary." --Linwood Barclay
The heart-stopping second novel from the author of Nightwatching, in which a father-son ski weekend becomes a desperate fight for survival
Twelve-year-old Zach is cautiously optimistic. His father Bram, whose business is in dire need of cash, has put together a father-son backcountry ski weekend to wine and dine his biggest investors. Schooled in outdoor survival by his mother, Zach is eager to prove himself to the hypercritical Bram. Maybe if Zach shows how useful he is, he can earn his father's love.
But Zach knows to be on high alert around Bram, and he sees the way the group ignores the increasingly threatening conditions. For the first time in his beloved mountains, he is faced with the unknown, convinced that something watches their cabin from the treeline. Something that leaves behind strange tracks and picks its prey clean.
As the adults recklessly test the limits of the outdoors, Zach worries he might be in even more danger than he realized. Could the men around him prove more violent than the unforgiving weather, and the strange creature lurking in the dark? Zach will have to rely on his wits if he hopes to make it home safely. But he knows all too well that the wilderness can be unpredictable even at the best of times. And at the worst? Deadly.

This is an awesome story. It kept me on the edge of my seat though the entire story. The ending was surprising and yet very satisfying. I will be excited to read more books by this author.
I enjoyed this book but unfortunately, I didn't love it. I didn't feel drawn in to the story. I'm sorry.
Twisty and good, but more bad language in it than I like, so hard to recommend it. It had me almost believing in the abominable snowman or something.
Zack is the son of Bram. They are on a father/son ski trip with Bram's investors. The cabin used to be used by Zack’s mom for her wilderness survival lessons. With his mother gone, Zack must face dangers and use the lessons mom taught him to survive the biggest monster in his life. Good story flow, enjoyable read. I recommend.
