When the Moon Hits Your Eye — John Scalzi

From the New York Times bestselling author of Starter Villain comes an entirely serious take on a distinctly unserious subject: what would really happen if suddenly the moon were replaced by a giant wheel of cheese. It's a whole new moooooon.One day soon, suddenly and without explanation, the moon as we know it is replaced with an orb of cheese with the exact same mass. Through the length of an entire lunar cycle, from new moon to a spectacular and possibly final solar eclipse, we follow multiple characters — schoolkids and scientists, billionaires and workers, preachers and politicians — as they confront the strange new world they live in, and the absurd, impossible moon that now hangs above all their lives.
