Communications specialist Alto’s shift aboard the starship M.G. Yellowjacket turns hellish after waking from a tryst to learn every crewmate has vanished. Worse, a sinister presence has crawled aboard the ship. It’s violent, destructive, and it can reach into your thoughts to make you see and feel what it wants. Anxiety-ridden Alto might be the least-qualified person to face a creature that can hack minds like computers. Only a perilous journey to the ship’s bridge can reunite comms specialist with crew and give them a chance to call for help. But the intruder only scratches the surface of this crisis, and discovering the truth will bring Alto face to face against a nightmare beyond flesh and thought.
