Genius aerospace engineer Julia Hayes built everything from scratch with her husband Bryce Sterling ten years ago in their garage. Her self-developed Eden System lifted him to the throne of a commercial space empire. A decade later, on the very day she is diagnosed with ALS, she discovers the man who once loved her more than anything has long betrayed their marriage. Julia does not throw a fit or expose his secret. Instead, she quietly plans a farewell no one will know about: she revokes Sterling Aerospace’s commercial license for the Eden System, donates the core technology to NASA free of charge, and signs up for a one-way deep-space colonization mission. On the day Sterling Aerospace rings the bell for its IPO, Bryce thinks he has reached the peak of his life. But inside a gift box left by Julia, he finds the license revocation document, her terminal ALS diagnosis, and her contract for the one-way space mission. The stock price crashes instantly, and his commercial space empire crumbles. Meanwhile, the spaceship Eden One carrying Julia vanishes into a solar storm. Only after Julia is declared dead does Bryce realize he has permanently lost the woman who stood beside him when he had nothing — the woman he himself sent into the stars. No matter how hard he searches or repents afterward, all he can hear is endless cosmic static, waiting for a reply that will never come.
