What would you do with humanity’s second chance? Astromedic Evie Cunningham awakens from an unprecedented cryogenic sleep to find Triton transformed into a lush, habitable world. As she and the members of Mission Team 4020 explore their new home, one thing becomes heartbreakingly clear: the sun has expanded into a red giant, obliterating Earth—and with it, all of humanity. Now they must rebuild humankind in this paradisal world. But paradise has a price. A parasitic entity, exiled from a higher dimension, has found its way to Triton. It seeks not only to replace humanity as heir to the solar system—but to redefine what it means to be human. Evie and her team must unite to survive in a world as alien as it is beautiful. Among them: a physicist harboring a dangerous secret, a carefree engineer, a lonely chemist searching for connection, and a commander who knows far more than she reveals. Can they rebuild civilization before it’s consumed by a war against a being beyond comprehension? Or will their own hubris prove to be humanity’s final undoing
