Norma Christianstead is the first person raised from conception to adulthood in zero gravity. The year is 2200. She is a temporal savant. The goal is to determine how micro-gravity interacts with physical, intellectual, social and psychological development. Fifteen years later a CRISPR-spawned plague is overtaking Earth. Norma learns there is another goal to the experiment: to respond to the divinations of a secret artifact-a beacon-of an ancient civilization that vacated the Tharsian region of Mars a billion years earlier when the planet's seas evaporated. The response to the beacon demands nothing less than an epigenetic evolutionary alteration in Norma, for theTharsian genomic code is genophotonic: a hybrid consisting of physical and photonic parts. In this, Patrick Moran's fourteenth novel, the author comes to grips with how and why gravity and perception are related. In Zero Gravity Girl he weds the two in a tale that redefines the meaning of love and life, time and space.
