Game the system. Stick to the plan. Burn the whole world down. Boone is out of time. Drowning in debt, hunted across the stars, and haunted by the people he couldn’t save, he gambles everything on a tenuous future. But as he gets closer to uncovering Chelani’s insidious plans, his execution closes in. He knows his next mission is suicide, but he’ll do anything to take down the empire. Elyon is promised a pardon and a life more luxurious than she could imagine—but it comes with a price. Sent to silence Chelani’s rivals one by one, she carves a path through the empire while convincing herself it’s for Boone. When he vanishes, the illusion shatters.

3.5/5
An adventure across space and time! “The writing style is crisp, the book is well edited and contains a healthy splash of hard science mixed in with a nice story line (new discoveries, alien aggressors, a military in need of leadership and a bad guy you'll love to hate)... This offering does not disappoint.” ~ LawBoss While on maneuvers as part of the Panhelion Defense Command fleet near the moons of Jove, Scott Drumond, captain of the Strike Cruiser Targelion, finds his promising career unexpectedly blighted by events that nearly destroy his starship and dramatically change his fortunes. Scott’s nemesis arranges his court martial on trumped-up charges, and the court finds him guilty. Scott accepts temporary captaincy of the scout corvette Pegasus with the hope of restoring his honor and permanent rank. His assignment turns out to be anything but routine when, upon reaching the anomaly, he and his crew encounter a startling distortion in space-time that creates a barrier to material objects. With the first part of his mission complete, he opens sealed orders and learns of scheming and deception in the highest levels of the Panhelion. EVOLVED PUBLISHING PRESENTS the first book in the “Panhelion Chronicles.” This military science fiction series features space travel, time warps, alien contact, and war on a grand galaxy scale.
