Bryn Seymour was nine years old when her mother died under mysterious circumstances on the same day Apollo 11 made its historic lunar landing. Forty years later—divorced, working as an obituary writer, and duly cynical—she meets Howard, a conspiracy theorist who knew her mom and believes a small Texas town may hold clues to what really fueled her demise. Seeking closure, Bryn goes along for this men-in-black ride. But upon meeting Howard's son Sam, an outspoken Christian, she can't decide whose beliefs are more pie-in-the-sky.

The gravity of life has pulled Bryn down for decades. But a perfect love could be her first step to soaring. It only happens once in a blue moon.
