We’d almost made it to the rim when the row of mirrors opened like hatches and thousands of tiny metallic…things poured out. Annabeth screamed. It was an army of wind-up creepy-crawlies: bronze-gear bodies, spindly legs, little pincer mouths, all scuttling toward us in a wave of clacking, whirring metal. “Spiders!” Annabeth said. “Sp—sp—aaaah!” I’d never seen her like this before. She fell backward in terror and almost got overwhelmed by the spider robots before I pulled her up and dragged her back toward the boat.
