SILVER BADGE RECOMMENDED READ IN THE 2021 AUTHOR SHOUT READER READY AWARDS. A solar flare rips open the veil of reality and sets a collision course with destruction. The year is 3001, and Dr. Leigh Lybrand is excited to leave Earth to establish humanity off-earth. She kisses her fiancé goodbye, promising to return with a solid career and enough money to sustain them forever. Forever is cut short when a solar flare wipes out Earth as she and her colleagues arrive on the Jovan Station.
Soon, they begin to have visions of parallel universes that reveal an unsettling truth: the solar flare was orchestrated by a radical religious group planning Earth's destruction to usher in a new Paradise. When Leigh discovers ties to her fiancé, she's forced to make a choice: accept her fate, or use what she's learned to save humanity in some reality, even if it isn't her own.
