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.
Praise for Warning Signs:
“Tracy Sierra combines the forces of nature with the evil that men do to write an extraordinary double-whammy of a novel.”
—Linwood Barclay, New York Times bestselling author of Whistle
“As breathtaking as an avalanche, Tracy Sierra’s Warning Signs is a perfect mix of inner torment, warped masculinity, evil suspense, and the sublime. It kept me up reading late into the night.”
—Sierra Greer, author of Annie Bot
“Warning Signs is a truly unputdownable novel. Full of suspense and beautifully written, the book explores themes of wilderness, violence, and family ties with unusual subtlety. An enthralling book in every way.”
—Bruce Holsinger, bestselling author of Culpability
“An isolated setting and a pulse-pounding fight for survival combine to make Warning Signs a truly stunning novel.”
—Sian Gilbert, author of I Did Warn Her
“Warning Signs is the best thriller I have read in a long, long time. It is atmospheric, full of heart and so nail-bitingly suspenseful that it had me at the edge of my seat from page one. I devoured it as fast as I could.”
—Hildur Knútsdóttir, author of The Night Guest
A razor-sharp thriller about a mother forced to the breaking point when her life and the lives of her children are threatened by an intruder
Home alone with her young children during a blizzard, a mother tucks her son back into bed in the middle of the night. She hears a noise—old houses are always making some kind of noise. But this sound is disturbingly familiar: it’s the tread of footsteps, unusually heavy and slow, coming up the stairs.
