Challenge Met - The Sand Wars, #6

No suit, no soldier.and Jack has sacrificed the battle armor that has been his partner for decades. Branded a traitor, Jack Storm is brought before Emperor Pepys and the Triad Throne. St. Colin of the Blue Wheel is missing, taken by the mysterious alien Ash-Farel, with nothing more to protect him than Jack's old armor. Jack is tasked to carry out a rescue mission not just for one man but an entire galactic empire.
Pepys needs the Walker saint Colin found and brought back or political furor and civil war will topple the government. As promised, Jack has been reunited with his long-lost memories taken by the Sand Wars but he has lost as much as he has gained. No longer the same fighter, hampered by a false imprint, as aliens bring the force of their might against all humanity, Jack has come to his last stand in the Sand Wars.
