The fifteenth, and final, novel in The Shadow Wars.
Greg Bishop finds himself in an all too familiar, and disturbing, situation: he has awoken in a cell with no idea of how he has gotten there, where he is, or why he has been locked up.
As he escapes and begins searching the area around him, he makes several horrifying discoveries. His closest friends have been captured by an unknown group, and so have many horrors from their past. Alien monsters and otherworldly creatures roam the halls, beasts that they all thought they would never have to face again.
Outnumbered, injured, and terrified, the survivors must battle against old foes, monstrous horrors, and the environment itself if they are to get out of this one alive...
