Holding up millions of pounds, would not be fun.

Okay, they meet up with the General, Artemis, Annabeth, and Luke. Come to find out, the General is Zoe's fathers, also known as Atlas. He was the one who was holding up the sky for centuries now, and he tricked Annabeth to hold it up, but she wa only a half-blood and is not as strong as a immortal, so that's why Artemis took it from her. (Also, it makes you get gray hair, if your not immortal) So, Annabeth has streaks of gray in her hair. See, if the sky touched the world the world would end or something like that, so that's why someone has to hold it up. But they need to trick Atlas into holding up the sky now, so Percy takes the sky from Artemis and they all start fighting each other. Percy is in a lot of pain, because holding up the sky is millions of pounds. When Atemis gets Atlas to come close enough to Percy, Percy drops the sky on Atlas's shoulders.
Thalia is fighting Luke and he is on the edge of the cliff now, and Thalia doesn't know what to do. But Percy stops her from wanting to help him and he bumps into her and he falls off the cliff. At the edge of the cliff, is a bunch of monsters tring to get up the mountain as fast as possible.

I have a prediction. I hope to see that they find Bianca. that would be great :)
