When ex-Army medic River Swift returns to Alaska for a life of solitude, she expects silence, snow, and a chance to settle. Instead, she finds a community on the edge – locals fighting to protect their land, and a powerful drilling company tearing into the thawing permafrost.

But when workers begin collapsing with an unexplained sickness, River uncovers a terrifying secret buried beneath the melting ice. Something ancient, yet now engineered, and lethal.

Nordwell Energy is sealing off the town, and the polar night is plunging the region into endless darkness. Now River joins forces with her ex-fiancé, Navy SEAL Jason Wayne. As they race to expose a conspiracy capable of burning the Arctic – and the world – to the ground.
