Spin off from Hugh Howey's World of WOOL... Seventeen years ago, the California delegates to the National Convention were herded underground and locked into a silo while bombs exploded overhead. They’ve all done their best to survive since then—some of them with the help of mind-numbing drugs pumped into the water supply. Now, the head of IT is dying, and the people around her believe they should have a say in who her replacement will be. They aren’t aware that this isn’t a democracy, that they’re all being watched from somewhere else, and that Laura Wayne has already chosen her successor. She’s picked 24-year-old Connor Brownell, the stepson of the mayor—but Connor has secrets of his own, hidden deep inside the silo. There’s someone else down below, a man who’s carefully bided his time for all these years. He’s made himself essential to those around him, and when he finally decides to head upstairs with all those followers at his heels, he may not only discover a painful truth, he may destroy everything.
