The end of Earth wasn't loud. It was forgotten.
In a dying world suffocating under its own ashes, seventeen-year-old Riven Kade scavenges for scraps and survival-until a crash in the desert unearths a myth whispered in outlaw graffiti: The Planet Key.
Said to be forged by the Seven Species of the Dawn Pact, the Planet Key is more than legend-it can resurrect worlds, rewrite physics, and reshape reality itself. But Riven doesn't want to be a hero. He just wants clean water and a way out.
That changes when the shard fuses to his palm and paints a target on his back. Now hunted by alien warlords, void-born ghosts, and secrets older than memory, Riven must follow a galactic trail of shattered worlds, ancient trials, and buried truths.
As the pieces of the Key awaken, so does something else-something that remembers every mistake the galaxy ever made.
Some doors should never be opened.
Perfect for fans of Dune, Star Wars, and Red Rising, The Last Planet Key is a cinematic sci-fi odyssey of survival, memory, and destiny at the edge of extinction.
