Coincidence

Put twenty-three strangers in a room, and the universe has already decided that two of them share a birthday. You just haven't been introduced to it yet. We've all felt it. You think of an old friend, and the phone rings. You learn a strange new word, and it follows you for a week. You open a book you've never touched and find a dead relative staring back from the page. For half a second, the spine prickles and a voice whispers: this means something. Does it? Coincidence is a slow-motion ambush. It begins by arming you with mathematics so sharp you'll feel inoculated — the Birthday Problem, the Law of Truly Large Numbers, the elegant proof that the impossible is, in fact, inevitable. You'll feel safe. You'll feel certain. And then, chapter by chapter, the certainty starts to crack. Travel from a Stanford magician who turned probability into miracles, to a courtroom where a coincidence sent an innocent person to prison. From the eerie novel that predicted the Titanic fourteen years before she sank, to a five-thousand-year-old king who counted the floods of the Euphrates, found the number seven, and built a city that still stands. Each story tightens the screw. Each answer opens a darker question. Because this book isn't really about whether coincidences are real. The math settled that long ago. It's about the gap — the space between the shiver that runs down your spine and the spreadsheet that says it was always going to happen. That gap is wider than you think. Older than you think. And once you start looking into it, you can't stop. Fair warning: as you read, you will begin noticing coincidences. The number 7 everywhere. A name twice in one day. You'll wonder if the book did it. It didn't. You did. You picked up a book called Coincidence. You could have picked up anything else. You didn't. Was that a coincidence? Ask again when you're done.
