The Last Enclave

Still reeling from the death of his parents, Jake finds a doorway to an abandoned space station in his grandfather's basement — and when he walks through, he discovers he's trapped there with company. The station's AI enlists Jake to reclaim the systems needed to support life, but he has only eight hours or he'll die alone in the cold vacuum of space. With only a wrecking bar, work boots, and basic survival equipment, he must defeat the horrific monsters infesting the station before his air runs out — and deal with a hidden message that could spell doom for Earth and the entire universe.

Hordes of alien monsters are breeding on Pluto and the shield protecting Sol is failing. After his triumph on Pax, Jake returns home to Earth, where his grandfather hid an outpost in far northern Canada that may hold the solution. The town sheriff thinks he's an imposter, unnamed government agencies would love to vivisect him, and powerful forces lurk in the shadows. Even with his grandfather's powerful legacy, Jake must find a way to stop the threat to Earth.
