Kronos - Distorts Time Around Manhattan

“What’s happening with the mortals outside Manhattan?” I said. “Is the whole state asleep?”
Annabeth frowned. “I don’t think so, but it’s strange. As far as I can tell from these pictures, Manhattan is totally asleep. Then there’s like a fifty-mile radius around the island where time is running really, really slow. The closer you get to Manhattan, the slower it is.”
She showed me another scene—a New Jersey highway. It was Saturday evening, so the traffic wasn’t as bad as it might’ve been on a weekday. The drivers looked awake, but the cars were moving at about one mile per hour. Birds flew overhead in slow motion.
“Kronos,” I said. “He’s slowing time.”
“Hecate might be helping,” Katie Gardner said. “Look how the cars are all veering away from the Manhattan exits, like they’re getting a subconscious message to turn back.”
“I don’t know.” Annabeth sounded really frustrated. She hated not knowing. “But somehow they’ve surrounded Manhattan in layers of magic. The outside world might not even realize something is wrong. Any mortals coming toward Manhattan will slow down so much they won’t know what’s happening.”
