Caroline Blake longs for a night under a cloud-free sky with the telescope of her dreams. Busy, happily single, and passionate about her hobby, her life is as ordered as the science classes she teaches. Lizzy Carter is living the life she'd longed for. With a lively young family, an adoring husband, good friends, and almost enough money, she appears to have it all. Antonia Clarke is a divorcee with a teenage daughter, an ailing car, an obstinate mother and a lodger she needs to placate. She longs for twenty-four uneventful hours - but the gods have other plans. When the engaging Tom Grainger moves into each of the women's lives, things start to change. Three women whose paths have already crossed, find their fates are about to collide.
