The Circuit

"A hard-charging opener to a promising, if bloody, space-opera series." —KIRKUS


Centuries after Earth was rendered an uninhabitable wasteland, humanity was forced from its homeworld and founded the Kepler Circuit, a string of colonies throughout the solar system. These settlements provide resources to the remnants of humankind, the most important resource being the newly discovered element—Gravitum—found only in the Earth’s unstable mantle.


But a powerful religious faction known as the New Earth Tribunal has risen to preside over most of the Circuit. Though there is barely a faction left to challenge them, a string of attacks on the Tribunal’s freighters causes them to suspect their mortal enemies, the Ceresians, of foul play.


Tasked with solving the problem is Sage Volus: Tribunal Executor. Spy.


Sage quickly infiltrates the ranks of a roguish, Ceresian mercenary named Talon Rayne, seeking to discover the truth behind the attacks, but the longer she works amidst Talon and his squad, the more she finds her faith in the Tribunal tested.


While her quest for answers only unearths more questions, a new threat is on the rise, and it plans to bring down the Tribune once and for all.

Published 15 March 2016
In the thrilling sequel to The Circuit: Executor Rising, Cassius Vale has drawn the Circuit into open war.



After arriving on Ceres Prime, ADIM, ever the loyal companion created by Cassius Vale, is hesitant to help the Ceresians. Their hatred for his Creator will never wane and he starts to understand the danger all of Cassius' many rivals pose. ADIM must realize the true magnitude of his abilities in order to keep him safe.



When Sage Volus finds herself a captive of Cassius, she begins to struggle with her role in the coming war, and what exactly it means to be an Executor. The removal of her cybernetic implant reveals emotions she thought she'd buried too deep to be found. She must make a decision on who she truly wants to serve: Cassius Vale, The Tribune, or herself.



After breaking free of the Solar-Ark Amerigo and certain death, Talon Rayne finds himself in unusual company. His quests to hold his daughter again brings him to places he never thought he'd go-into the very arms of his people's most hated foe.



As the battle grows ever closer, threatening the all-out war that could annihilate millions, these four must determine what part they intend to play, who they will align themselves with, and what it means to be human in a universe where that means less and less.

Earthfall: The Circuit

by Rhett C Bruno

Published 29 December 2016
The conclusion to Rhett Bruno's stunning science fiction epic series The Circuit, which the San Francisco Book Review called "space opera that fans of Firefly and its ilk will appreciate."

Earth is uninhabitable, but beneath its ruined surface sits massive deposits of Gravitum, a powerful, dangerous element with the ability to generate artificial gravity. Whoever controls the element can control the settled regions of our solar system, now known as the Circuit. For centuries the peoples of the Circuit endured an uneasy, if peaceful alliance designed to share resources. Now the Tribunal, a religious order, is nearly ready to take over all of it. With only the reconvened band of Clans inhabiting the asteroid belt known as the Ceresian Pact standing between the Tribunal and system dominance, one man––Cassius Vale––intends to end their oppressive rule. Vale’s brutal and brilliant plan is nearly complete.

In order to gain more time to complete preparations, Vale builds an army under the control of his robotic creation ADIM in order to attack one of the leaders of the Tribune. ADIM loves his creator, but is growing more independent by the day, and soon may be too powerful for anyone to stop.

Talon Rayne, a mercenary, teams up with Sage Volus, a former Tribunal spy, when Talon discovers that his daughter has been captured by the very Tribunal leader Cassius Vale is after. Together, they have no choice but to ask for Vale’s help in saving her. Vale agrees, but are they just another cog in his scheme for bringing down the Tribune, or is there a part of him left that cares about anything other than vengeance?
