Eternal Flame. The Stellar Heart Series, #6

The universe has noticed. Aurelia's power has grown beyond the limits of a single world, sending a signal into the dark-and something has answered. An ancient force known only as the Void begins to consume everything in its path, drawn to the energy she cannot contain. For the first time, Aurelia faces something she cannot overpower. Something that doesn't burn. Something that erases. As entire regions fall into nothingness, humanity's last hope rests with the very being they once feared most.
But Aurelia is running out of time-and out of self. To stop the Void, she must do what she's resisted from the beginning:Let go of what remains of her humanity.and become something entirely new. Because in the end, the only thing stronger than destruction.is transformation. AI assisted for character history and story plotting
