Tenacity

All they want is a ride. Why is that a really bad idea? Former captain Lyn Randall is the only person on Earth who has the information to build the machine that can open a traversable wormhole. More accurately, she has the data. Her wife, astrophysicist Diana Teegan, pioneered the technology. They believe nothing good can come from humans expanding into the galaxy given how Earth has been exploited. So, they've vowed to keep it secret despite powerful entities within and outside government who will do anything to get their hands on it. But when a close family member makes an incredible revelation and a startling request, Lyn and Diana must decide whether to resurrect this device, leading to confrontations with old friends turned enemies and old enemies turned potential allies. Racing to stave off a galactic crisis, Lyn has to make split-second decisions about whom she can trust—to protect her family, herself . . . and Earth. This sequel to the award-winning Endurance takes Captain Lyn Randall and her crew on a daring adventure from Earth to the stars—one that questions the very nature of what it means to be human.
