The Last Reaper

When a high value scientist is taken hostage inside the galaxy's most dangerous prison, Halek Cain is the only man for the job.
The last remaining survivor of the Reaper program, Hal is an unstoppable force of fuel and madness. A veteran amputee-turned-cyborg, he has a history of violence and a talent for killing that is unmatched by any soldier.
With the promise of freedom as his only incentive, he’ll stop at nothing to earn back his life from the people who made him, imprisoned him, and were too afraid to let him die.
