Enter an edge-of-your-seat nightmare to the darkest frontiers in Crawlspace, a sci-fi horror novel from New York Times bestselling author Adam Christopher, perfect for fans of S.A. Barnes and Event Horizon.

Mission Lead Olivia O’Connor and her team from the Artemis Corporation, along with their military liaison, are in the final preparations for an undertaking that will alter the course of human history: a test flight that promises to open up new frontiers in the expanse of the universe.

But their journey between dimensions is one they never trained for. Strange voices in the corridors. Long lost faces not forgotten. Strange symbols carved into the hull. And gathering outside the ship, ancient forces beyond reckoning.

The crew will need all their skills to survive and uncover the twisted truth behind their mission.

Commencing countdown...
