One's Aspect to the Sun - Nearspace, #1

Captain Luta Paixon of the far trader Tane Ikai needs to know why she looks like a woman in her thirties-even though she's actually eighty-four. She isn't the only one desperate for that information. The explanation might lie with her geneticist mother, who disappeared over sixty years ago, but even if her mother is still alive, it's proving to be no small task to track her down in the vast, wormhole-ridden expanse of Nearspace.
With the ruthless PrimeCorp bent on obtaining Luta's DNA at any cost, her ninety-year-old husband asking for one last favoru, and her estranged daughter locking horns with her at every turn, Luta's search for answers will take her to the furthest reaches of space-and deep inside her own heart. "Debut novelist Ramsey uses classic science fiction tropes, but her setting cradles a more personal story of family trust and conflict." - Publisher's Weekly
