It’s shocking to wake up in one world and find yourself in another by nightfall, but the situation isn’t actually all that unusual. You wake up married, then your spouse dies over the course of the day; you wake in peacetime and by noon your country is at war; you wake in ignorance and by evening it’s clear that a pandemic is already here. You wake on a book tour with several days left to go, and by evening you’re racing toward home, your suitcase abandoned in a hotel room.
