For Dr. Siena Dupont and her ambitious team, the Alpenglow glacier expedition is a career-defining opportunity. But thirty miles into the desolate Deadswitch Wilderness, they discover a missing hiker dangling from a tree, and their satellite phone fails to call out.
Then the body vanishes without a trace.
The disappearance isn't the only chilling anomaly. Siena's map no longer aligns with the trail. The glacier they were supposed to study has inexplicably melted. Strange foliage overruns the mountainside, and a tunnel within a tree hollow lures Siena to a hidden cabin, and a stranger with a sinister message...
Holden Sharpe's IT job offers little distraction from his wasted potential until he stumbles upon a decommissioned hard drive and an old audio file. Trapped on a mountain, Dr. Siena Dupont recounts an expedition in chaos and the bloody death of a colleague.
Entranced by the mystery, Holden searches for answers to Siena's fate. But he is unprepared for the truth that will draw him to the outskirts of Deadswitch Wilderness-a place teeming with unfathomable nightmares and impossibilities.
