In 1997, a satellite engineer fearing for his life hid a floppy disk containing three incriminating photos in an access door of a GPS satellite in order to put the photos "out of reach." In 2021, private space contractors are hired to remove 2,600 obsolete, useless satellites from earth's orbit. The satellite, a.k.a. Maggie 316, is mysteriously recovered instead of being incinerated. Four strangers become a formidable team to solve the mystery of the three photos and to discover who had been willing to murder in order to keep the photos secret. As the story unfolds the reader is subtly a witness to the triumph of courage, the power of friendship, and the growth of real love in the midst of tension and uncertainty.
