Mortis

The aliens inadvertently turned Earth into hell.

Like the first Europeans to arrive in the New World, the aliens carried viruses, one of which mutates after contact with a terrestrial virus. The resultant plague makes humans into zombies and turns the aliens into the horrifying Xenomortis.

Seventeen-year-old Miles lives with others in relative safety in an isolated Texas town. Beating back the odd zombie attack and avoiding the Xenomortis is the new normal. But now a new threat has arisen, and when it destroys his community, Miles and his group must face the mayhem of the outside world as they battle to save what’s left of humanity –– and kill as many zombies as possible while they’re at it.
