Dead of Winter

Amazing! Perfect for the season. (I'm doing a winter horror thing this month).
9 strangers are stuck in a rural cabin in one heck of a storm.
Krista (Coates loves “K” names, doesn't she?) and her boyfriend Kiernan (see?) are on their way to a lodge when the storm hits. They get separated and Krista ends up in a cabin with 8 strangers. But not for long, because someone or something is picking them off one by one.
Three words: tree of heads
Twist after twist here.
