An alien invasion military science fiction series from #1 Amazon bestseller T.R. Harris.

The ultimate soldier is no longer under control.

In a galaxy consumed by a brutal war against the fanatical Antaere, humanity’s survival depends on the REV Warriors. Super-soldiers “revved” to superhuman levels by the performance-enhancing drug NT-4.

For fifteen years, Gunnery Sergeant Zac Murphy has been the tip of the spear, enduring over a hundred combat drops into enemy territory.

But after a lifetime of death and drugs, he’s changing.

Zac’s body has begun to produce its own natural form of NT-4. He’s no longer just a soldier; he is a mutation with ten times the strength of a normal Marine and a mind that remains conscious even in the heat of drug-induced battle rage.

A weapon that thinks for itself is a weapon high command cannot allow to exist.

Betrayed and exiled to the savage prison world of Eliza-3, Zac is left to rot on a planet of nightmare predators. But the Antaere war is far from over.

Zac is offered one last chance at redemption: a suicide mission into the heart of the alien menace’s most sacred fortress alongside a hand-picked squad of elite “Charlie” REVs. No dose. No rules. No mercy.
