Project Harvester (Ready, Aim, Fire! #1)

Earth is dying.
Jace Riven has five years to live.
He only needs two to save humanity.

In a future where Earth is scorched and civilization lives underground, solo harvesters risk their lives mining hostile alien worlds for vital resources. But when Jace, a terminally ill nobody, volunteers for the mission, no one expects him to last a week.

Armed with a basic suit, a weak rifle, and a ticking clock in his DNA, Jace must survive savage alien wildlife, deadly terrain, and other harvesters — all while unlocking mysterious tech upgrades and outsmarting an evolving enemy.

The deeper he goes, the stronger he becomes.
But the clock is always ticking.
