Challenger Park — Stephen Harrigan

At the novel's center: Lucy Kincheloe, an astronaut married to an astronaut, the loving mother of two young children, with a fierce ambition to excel in the space program. Her husband, Brian, a rigorous man whose dreams of glory have been blighted by two star-crossed missions. Walt Womack, the steady, unflappable leader of the training team that prepares Lucy for her first shuttle flight.

Lucy has devoted years of intense and focused effort to win her place on a mission, but as her lifelong dream of flying in space comes true, her familiar world appears to be falling apart around her. Her marriage is deteriorating. Her son's asthma is growing more serious. Her relationship with Walt Womack is becoming dangerously intimate. And when at last she is in space, 240 miles above the earth, and an accident renders the world she left behind appallingly distant--perhaps unreachable--her spirit is tested in gripping and unexpected ways.
