Genesis Horizon by Justin Scheide

In a future where Earth faces imminent collapse, the colossal colony ship, the Citadel, becomes humanity’s last hope for survival among the stars. When the ship is knocked off course with its citizens and crew in cryostasis, the ships AI takes matters into its own hands, selecting a new home for humanity’s last stand. The ship’s diverse crew harbor their own secrets and motives as they navigate the cosmos. However, the great rebuild takes an unexpected turn when a faction of cybernetically enhanced defectors, the Marauders, emerges to wreak havoc on the new galaxy.

Uncertain of their true intentions, trust fractures within the Citadel’s walls, raising the question: Is the enemy among them, or beyond? As the crew grapples with this existential threat, they embark on daring missions, unravel mysteries, and engage in epic space battles.
