Stripped of her power and stranded in space, Nadia Khan just leveled down in her worst isekai yet.

Once a mermaid queen with elemental magic, Nadia wakes up rebooted as a powerless teen in a brutal sci-fi galaxy—thanks to the same rogue quantum AI that summoned her from Earth. Her shattered Ring of Power is scattered across hostile worlds, and every fragment is guarded by something that wants her dead.

In a realm of pirate warlords, forgotten ruins, and game-infused tech, Nadia’s only hope lies in reuniting with her hacker brother, dodging bounty hunters, and mastering a new combat system that punishes mistakes with permanent death.

The AI calls it a "quest." She calls it survival.

But as Nadia explores spaceports hidden in bubble cities, escapes derelict ships haunted by glitching defenses, and faces down a dragon-riding space tyrant, she starts to wonder: was she summoned to save the galaxy… or destroy it?

If you love isekai sci-fi, reluctant heroines, and D&D-style leveling in hostile alien worlds, this next chapter in The Quantiverse is your next obsession. Fans of Cradle, Re:Zero, Arkhnemesis, and The Expanse will love this space-fantasy thrill ride.
