Sometimes, it takes a crisis to figure out who you really are.

In the near future, an irreverent astronomer named Marcus Donovan discovers a strange relic hidden beyond Mars, and commandeers an exploratory vessel under false pretenses to investigate.

While Marcus and his crew venture off into the unknown, a mysterious alien legion appears in Earth orbit and invades. Human civilization is dashed apart in the blink of an eye, and search and rescue specialist Jack Hernandez is one of the lucky few to survive. Along with a handful of friends, Jack joins the scattered resistance and wages a desperate terrorist war against the aliens, striking back any way they can.

In the bloody struggle to reclaim their planet, Jack and Marcus are each thrust into roles they never could have imagined in a conflict as old as time. The fight takes them from China to Africa, and from Earth to Mars, while the secrets they uncover shake their understanding of humanity itself.
