Human For Hire Book 4

Available Online At These Stores


“Best Human for Hire book to date!”

The Human racks up the score in this one…

That’s because when you run out of options, all you can do is …

Kill them. Kill them all.

When The Human takes on a minor mercenary job of protecting a group of settlers against alien marauders, it seems simple enough … until the bad guys don’t take no for an answer, leaving Adam with only one option…

Kill them, kill them all.

Get ready for The Magnificent Seven in Space.

He wasn’t supposed to care for the helpless aliens; that’s not his line of work. He deals in lead … and flash bolts. But maybe Adam’s getting soft in his new cloned age. Yeah, I don’t think so. He just has a thing for the underdog. Get ready for some major alien ass-kicking as the marauders do the one thing you shouldn’t with Adam Cain. They made him mad.

Now, time for some serious collateral damage!

The pace is electric and the action non-stop in Human for Hire (4) – Frontier Justice, as we follow the continuing adventures of Adam Cain: The Human for Hire.

More about Human for Hire

After the galaxy was savagely attacked by invaders, the Milky Way was left but a shadow of its former self. Gone are the vast empires that once brought stability, law and order to countless star systems. In its wake, a savage existence ruled by gun and muscle. And for anyone needing help in either the gun or muscle category—or both—everyone knows you … Hire a Human.

Humans have a reputation for being the baddest of the badasses. Stronger than most, skilled at the art of war and other chicanery, Humans once ruled a vast stellar empire of their own. Not any longer. Now, most of them have retreated to Earth to rebuild after the devastating Klin invasion. Now, only a few hardy Humans still wander the space lanes in search of work.

Human for Hire is the latest series by science fiction author T.R. Harris, the creator of The Human Chronicles Saga and the REV Warriors Series, perennial favorites on Amazon for over 11 years. Filled with non-stop action, side-splitting pop-culture references and a menagerie of exotic characters, Human For Hire is the next great series in science fiction today.
