Executor Rising

"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."
