The world—the human part of it—had been gelded or maybe turned barren—perhaps both—and people just stopped having kids. That’s all it took. The Lastborn generation—the Baby Bust as they called themselves, proving that irony was one of the last things to perish—they just carried on getting older and older until they died like people always had done. And when they were all gone, that was it. No bang, no whimper even. More of a tired sigh.
