Warning Signs

"Nerve-shredding. . . . What could have been a pure tale of icy survival is enhanced by [Sierra's] thoughtfulness." --The New York Times

"The tension, the atmosphere, the dread . . . This is a book that sticks in your head long after the last page." --Lisa Jewell

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.
