Endeavor

From publisher blurb: Russell is a military aviation officer given the opportunity to fly like he had always dreamed as test pilot for an experimental exo-skeleton program. Picking up an emergency call in one of his early test flights, he responded and saved the lives of many people. The positive media coverage helped him convince the tech company he worked for that publicized heroism was a PR opportunity like no other... and it allowed him to fight the good fight and live up to his ideals at the same time. With gravitic flight and potent particle beam projectors, the armored hero ENDEAVOR is here to save the day!
