Cowboy Nathan resigned himself at seventy-five years of age to spend his last days in Shady Hills Retirement Center reading old westerns and trying to stay in good enough shape to avoid adult diapers.

Widowed and with busy adult children, his tendency to fall at odd times made him too much of a burden. Right up to the night of his first mission with the Earth Protection League.

Suddenly he found himself young again and a captain of a fighter, with a new crew, going up against the alien Ticks as they swarmed over the border to take EPL planets.

He sure enjoyed popping Ticks and saving Earth at the same time.
