Ian Stevens, director of the Deep Space Research Institute, isn’t interested in conducting research just for the sake of research. While the rest of the world - including the US Government - thinks that’s the DSRI’s sole mission, Stevens is actually interested in more - he wants manned space travel and the colonization of the moon. With NASA defunct, few scientific probes are being launched, and no one even talks about human spaceflight anymore. Stevens is out to change that.

Nora Devi is a xeno-archaeologist with a complicated past. She has buried more secrets than she’s dug up. Widowed in the recently ended twelve year war between Capitoline and Palantine, she now makes a living as an independent tagger in border space.

This is the story of Leif Grettison, a crew member of humanity’s first flight to the stars, even though he had not expected to take that trip. The year is 2069. The Troubles, a decade plus of proxy, and direct warfare among the US, Russia, and China, had brought the world to the brink of apocalypse. It was close enough to finally scare the leaders of the powers into signing the Geneva Treaties, a set of agreements pledging peace, cooperation, and the dismantling of the military complexes.

TWO HOSPITAL BEDS in a Stanford University lab. Two still figures, attached by bundles of cables to the experimental QARMA supercomputer. Analise and Wolfe are true scientific pioneers, the first humans to ever leave the shells of their physical bodies to explore an entirely new virtual universe beyond time and space. But their creation, the most vivid VR metaverse ever envisioned, has come under attack.

For years, while Iran and North Korea kept Western diplomats busy, China and Russia have been quietly seeding the US with spies and soldiers. Now, a silent army of occupation lurks inside US borders, and for America, it is already too late. When the assault begins—via an EMP strike that disables the US electrical grid and neutralizes her defenses all in one fell swoop—the US is caught completely unprepared. The nation is lost, and it is up to ordinary citizens to defend their cities, towns, neighborhoods, or even just their families.
