The Great Outer Dark - The Midnight Games, #3

The electrifying conclusion to the Midnight Games trilogy. Aboard the airship Sorcerer, Nate Silva rides a galaxy-spanning continuum threshold on a dangerous rescue mission to the home planet of the hideous Great Old Ones. But returning to Earth, Nate finds Hamilton in the grip of a newer, stronger Resurrection Church of the Ancient Gods and a mind-controlling monster called Oracle. Caught in the middle are Nate's friends and a mysterious double agent, the enigmatic Dr.
Eldritch. To rescue the city, and the world, Nate and his companions fend off dritches, night-gaunts and the shape-shifting Old One Nyarlathotep, then hijack Sorcerer for one last voyage to save themselves and their loved ones from the hostile forces that Nate's friend H. P. Lovecraft describes as "the great outer dark."
