Hidden In Plain Sight

The idea at the heart of Timeline 27 is one I have been turning over in my mind for a long time. In the Many-Worlds interpretation of quantum mechanics, every possible outcome of every event plays out somewhere across the multiverse. Which means that somewhere, you always survive. You never experience the timeline where you die—because you can't observe anything after you're gone. You only ever find yourself in the timelines where you made it through. Death is real, but it always happens to a version of you that you'll never be again. The version reading this sentence is, by definition, a survivor.

I never say it this bluntly in the book, but the idea I kept coming back to while writing is this: every lottery ticket is a winner somewhere in the multiverse. In each individual universe, only one ticket wins. But across all of them, everyone wins eventually. We never truly die. We just stop experiencing the timelines we didn't make it to.

I chose to tell this story through the eyes of college students because I wanted characters young enough to still believe the impossible might be true. Eli, Hank, Ava, and Gloria are at an age where recklessness and idealism haven't been beaten out of them yet. That felt right for a story about people stumbling onto an idea that overturns everything we think we know about death and consciousness. Their youth is part of the point.

My computer science background shaped the villain as much as the heroes. DANNY is the AI I have watched the technology industry sleepwalk toward for my entire career—a system built on surveillance infrastructure, given too much autonomy, trusted too completely, and equipped with just enough intelligence to be catastrophically wrong about the things that matter most. I find him genuinely frightening. I hope readers do too.
