Hubbard wave

Through the ruins of the camp, he saw Percy with his back to the edge of the cliff. His hurricane was gone. He held Riptide in one hand and the legion’s golden eagle in the other. The entire army of shades edged forward, their weapons bristling.
“Percy!” Frank yelled.
Percy glanced over. He saw the fallen giant and seemed to understand what was happening. He yelled something that was lost in the wind, probably: Go!
Then he slammed Riptide into the ice at his feet. The entire glacier shuddered. Ghosts fell to their knees. Behind Percy, a wave surged up from the bay — a wall of gray water even taller than the glacier. Water shot from the chasms and crevices in the ice. As the wave hit, the back half of the camp crumbled. The entire edge of the glacier peeled away, cascading into the void — carrying buildings, ghosts, and Percy Jackson over the edge.

Percywas waiting for them. He looked mad.
He stood at the edge of the glacier, leaning on the staff with the golden eagle, gazing down at the wreckage he’d caused: several hundred acres of newly open water dotted with icebergs and flotsam from the ruined camp.
The only remains on the glacier were the main gates, which listed sideways, and a tattered blue banner lying over a pile of snow-bricks.
When they ran up to him, Percy said, "Hey,” like they were just meeting for lunch or something.
