It’s a name that strikes terror throughout the Milky Way…

The Mad Aris Kracion.

And now he’s back … and working with Adam Cain. What could go wrong?

International Bestselling Science Fiction author T.R. Harris brings you the 6th and final book in The Human Chronicles Legacy Series.

Allied Command

... an Adam Cain adventure.

The alien with an attitude is BACK!

And he’s not the only one. Kracion, the Mad Aris , is also back, and working with the allies to stop the Klin from destroying the universe. As the Klin build and deploy thousands of trans-dimensional starships, they refuse to accept the danger the space engines represent. Kracion has spent years repairing the damage to the space/time continuum caused by these drives, and now the Klin are literally tearing the fabric of space apart even worse than before..

Adam Cain and the allies have tried everything to stop the Klin from using the warcraft, but to no avail. Now it’s Kracion’s turn to convince them. And as their former living God, he has a pretty good chance. But is that all he’s here for, to help the allies? Or is he here to help himself? Adam has his work cut out for him keeping a tight reign on the insane, immortal Aris, with nothing at stake except a second Big Bang if he fails.

Allied Command is the 6th and final book in The Human Chronicles Legacy Series. This is where it all comes together, where past villains and reluctant heroes clash as never before. Hold onto your seats. This ride is going to be wild!

End of an era and the beginning of a new one

TR Harris has written the final book in his chronicles. Six books for an intertwined storyline. Lots of adventure and many plots twists and turns as Mr Harris is good at. Nice to see an adventure in six books wrap up, as much as any TR Harris story ever wraps up. Jay and Summer became an item. Can’t wait for “ Human for Hire” to begin. Join TRs Facebook for even more fun and a few related virtual adventures. The Dino hunt is about to begin!

Adam Cain is The Human

The Human Chronicles Legacy comes to a closer with the death of immortals and universes. The Klin and the Mad Aris Kracion are destroying the Milky Way and Newfound Universes. The tears in the fabric between universes will soon collapse and destroy both universes! Unless, of course, The Human and the immortals can make emergency repairs.
Our favorite humans, Juireans, Klin and Aris do their usual - kicking butt and taking names. All good fun must come to an end. And they do! This is a great read!
