Their actions put the Hollow and its residents in danger of the King’s wrath. Nothing will stop his mystical plans. As the celebration of the Hollow’s Eve draws nearer, powers are growing. Ancient beings unseen for generations descend the mountains. If the King is not stopped it could mean the end of the world.

Into the Void by Michael Lupton

It was supposed to be another day of retirement, until the government finally tracked down Langer to his hiding place in a quiet Bavarian town. Whether they wanted to pull him back into service or imprison him for his crimes, he would not go willingly. What he faces instead is far more horrifying than the two possibilities combined. Hunted down for their skills, Langer, and others like him, are taken to a place known by no others to exist. There are things that lurk in the darkest places of space and the mind. Now Langer and his marooned companions must struggle to survive threats far greater than themselves.
