If Terra is humankind’s last hope, Sera doesn’t see a way forward. Her entire life has been aboard a space station on the far side of a planet with air she can’t breathe and pressure she can’t bear, despite fifty years of work on the planet’s surface. She has never been happy on Terra. When Cam, the person she was supposed to spend her life with, shares a secret that changes everything, it only gets worse. Sera has never seen the sun, felt a warm breeze, or heard the crash of waves against a shore, so she builds a virtual reality worth living in. She doesn’t want to make Terra home. She wants to escape. But when Earth begins its final evacuation, Sera realizes her ability to create worlds may be what saves them all.
