Answer:

Step-by-step explanation:
"We barely got out alive. I still have nightmares, Percy. The way that Cyclops
talked in my father's voice. It was his fault we took so long getting to camp. All the monsters who'd been
chasing us had time to catch up. That's really why Thalia died. If it hadn't been for that Cyclops, she'd still
be alive today."
