June and Ephraim Alcott were never prepared for the debilitating struggles of pioneer life on Glastenbury Mountain when they uprooted from their vapid lives in the South. With little food left in their cupboard during an especially harsh winter, Ephraim must leave to go hunting on the remote mountain, leaving June alone in their tiny cabin. When Ephraim does not return, June must spend weeks on her own, trying to survive amidst her deteriorating strength and sanity, starvation, and terrifying stories of the mountain circling in her mind. An odd encounter one night drives June's sanity to a breaking point as the horrors of Glastenbury Mountain finally reveal themselves.
