The eighth novel in The Shadow Wars.
After the events of Ceaseless and Snowblind, Allan Gray, formerly a member of Security-Investigations, now a Specialist in Special Operations, is having some trouble keeping sane. He experiences sudden tremors, inexplicable terrors, and is incapable of removing his suit of power armor, even for something as simple as a shower. He knows something is wrong, but refuses to let anyone else into his life.
All he wants is to keep doing his job, keep running missions and bury his head in responsibility so that he doesn't have to put up with his own problems. So when Hawkins comes to him with another dangerous job, he leaps at the opportunity.
Allan's new objective seems simple, on the surface: investigate a Rogue Ops ship found adrift in space. Intel is low, no one has any idea what happened to the ship or even what it was doing, but an opportunity to seize crucial data on the enemy is too good to pass up. Allan and a small team of experts are rushed out to the isolated vessel.
Upon arrival, the mission goes bad and Allan finds himself trapped on a Rogue Ops ship, facing down an enemy more insidious, more lethal than any he's ever encountered before...
