For people who make up stories for a living, that is the ultimate success: knowing that, when the book closes, when the series ends, the adventure is not over. It goes on without the creator, in the minds of the people who love it. You can’t stop the signal. Once it’s broadcast, it continues on forever, pulsing past star clusters, lighting up new worlds, collecting new fans, till the end of time itself.
