Living a Hard Life

At the beginning of the story Percy was dreaming about what is happening to his friend Grover, who is a satyr (someone who is half human-half goat).  A monster was chasing for him and he was telling Percy that he should go to save him from his death, because the monster made a trap and the satyr falled there. When Percy woke up he went to school, his friend was Tyson and there was a bully, his name was Matt Sloan.  That guy always made bad jokes to Percy and Tyson. It was time to play dodgeball at the school and Matt told them that he was going to hit them really hard. Percy couldn´t use his powers against normal people because he was a half-blood(half human-half god).

When they started playing, some monsters appeared at the gym and were trying to kill Percy by throwing balls to him, but Tyson threw them back and caused that the monsters vanish. After escaping from the school they took a taxi to half-blood hill, that is a place that protects half-bloods from monsters because it has magical borders. When they arrived there, a lot of monsters were attacking and all the half-bloods were fighting against them. The monsters hitted Clarisse and Percy, because they were both half-bloods but Tyson without being a half-blood was allowed to enter there and saved Percy and Clarisse. There was a tree that controlled the magical borders but it was poisoned, so any creature could enter there whenever it wants.

"Tyson had batted two of the balls back toward their owners and blasted them to ashes."(12)  How could Tyson control two balls at the same and hit the monsters to turn them to ashes? Does he have some special powers or what?
"He´s a Cyclops." Annabeth paused.(28) When Annabeth said that Tyson was a Cyclops I wanted to know if Cyclop
s were good creatures or were evil monsters.

It should be tough being a half-blood because you have a really busy life. Fighting against monsters is not easy and if something goes wrong you can loose your life. If someone is being bullied the first thing that he wants to do is try to protect himself and the fact of being a half-blood did not allow him to protect himself. I would not like monsters appearing in front of me at every moment, because I think that being killed is not nice. Will Percy defeat all those monsters or will the monsters end up killing him?
