Two hundred and twenty million years ago, a cosmic encounter wiped out the ancient civilization of Mars. Now, as the Solar System completes its slow orbit around the edge of the Milky Way, Earth is squarely in the crosshairs of the exact same celestial threat. The Savitar Collection is an epic, deep-time science fiction saga that balances the staggering scale of a planetary rescue mission with a profoundly human story of loyalty, survival, and love. Follow an extraordinary crew of four thousand souls as they cut ties with a fractured Earth, build a new civilization in the stars, and fight to transform humanity’s greatest crisis into a future of enduring hope.
