Briardark

For Dr. Siena Dupont and her ambitious team, the Alpenglow glacier expedition should be career-defining. Thirty miles into the desolate Deadswitch Wilderness, it becomes something else: they find a missing hiker hanging from a tree, their satellite phone dies, and the body disappears without a trace. Siena's map stops matching the trail, the glacier they came to study has melted away, and a tunnel through a tree hollow lures her toward a hidden cabin and a stranger with a sinister message.

In a parallel thread, underachieving IT worker Holden Sharpe stumbles on a decommissioned hard drive and an audio file: Siena's own account of an expedition collapsing into chaos and death. Obsessed, he goes looking for the truth—toward the edge of Deadswitch and its impossibilities. S.A. Harian's Briardark is a twisty cosmic survival horror, the cliffhanger start of a series.
