Jim Harrison is a test pilot in the United States Air Force, one of the exalted few. He spends his days cheating death in the skies above the Mojave Desert and his nights at his friend Pancho's bar, often with his wife, Grace. She and Harrison are secretly desperate for a child--and when, against all odds, Grace learns that she is pregnant, the two are overcome with joy. While America becomes swept up in the fervor of the space race, Harrison turns his attention home, passing up the chance to become an astronaut to welcome his daughter, Florence, into the world. Together, he and Grace confront the thrills and challenges of raising a child head-on. Fatherhood is different than flying planes--less controlled, more anxious--however the pleasures of watching Florence grow are incomparable. But when his family is faced with a sudden and inexplicable tragedy, Harrison's instincts as a father and a pilot are put to the test.
