"Look up! Look out! A comet is coming, a comet is coming! Stink is camped out in the backyard with his sister, Judy, and he can't wait to lay eyes on P/2015 OZ4, also known as the Sherman-Holm Comet. But then news of an asteroid hitting Russia reaches Stink, and suddenly he's feeling squeamish (and squash-ish) about close encounters of the outer-space kind. Will donning an aluminum-foil cape and building a bunker in the basement help keep him safe? Can this fearless Asteroid Boy save Earth from disaster?"--
