Sabine, the Intriguing Orange-Haired Woman, and the Family Mystery

When spending time with her family on Knowest, Sabine learned what she always suspected: that Ursa Wren was her stepmother and that her real mother is on a planet in the Milky Way Galaxy known as Earth. Armed with intel from the ever-elusive Fulcrum, Sabine begins a daring rescue mission to save the planetary inhabitants from certain doom caused by a new superweapon being tested by the Galactic Empire. She hopes to meet her birth mother in what portends to be an eventful reunion. When she gets to the frontier town of Miradero, however, it seems deserted...at first. She discovers that this is not the case. Later, she reunites with her birth mother, but learns something that shocks her beyond belief. Can she process it before the Empire obliterates her home planet?
