The Battle of the Labyrinth - Chain Escape

“Someone’s coming!” Rachel warned.

The doors of the workshop burst open, and Nico was pushed inside, his hands in chains. Then Kelli and two Laistrygonians marched in behind him, followed by the ghost of Minos. He looked almost solid now—a pale bearded king with cold eyes and tendrils of Mist coiling off his robes.

He fixed his gaze on Daedalus. “There you are, my old friend.”

[...]

“Get them,” I said. “I’ll try to buy you some time.”

And with that, all Hades broke loose. Annabeth and I charged at Kelli. The giants came right at Daedalus, but Mrs. O’Leary leaped to his defense. Nico got pushed to the ground and struggled with his chains while the spirit of Minos wailed, “Kill the inventor! Kill him!”

Rachel grabbed the wings off the wall. Nobody paid her any attention. Kelli slashed at Annabeth. I tried to get to her, but the demon was quick and deadly. She turned over tables, smashed inventions, and wouldn’t let us get close. Out of the corner of my eye, I saw Mrs. O’Leary chomp her fangs into a giant’s arm. He wailed in pain and flung her around, trying to shake her. Daedalus grabbed for his sword, but the second giant smashed the workbench with his fist, and the sword went flying. A clay jar of Greek fire broke on the floor and began to burn, green flames spreading quickly.

“To me!” Minos cried. “Spirits of the dead!” He raised his ghostly hands and the air began to hum.

“No!” Nico cried. He was on his feet now. He’d somehow managed to remove his shackles.

“You do not control me, young fool.” Minos sneered. “All this time, I have been controlling you! A soul for a soul, yes. But it is not your sister who will return from the dead. It is I, as soon as I slay the inventor!”
