The main story is about Percy, an unusual young boy, who has many odd and weird experiences. One day, he went to a museum (for)on a school trip, and there he watched his math teacher,who doesn't like him so much, change(d) into a terrible monster, that look(s)ed like a devil. As soon as she changed, she attacked him fiercely. Percy defeated her on impulse,with a weird pen.  (Upon the opportunity) At this moment, he recognized that he was the son of (between) Poseidon and a human woman. He was also (framed that he had stolen) accused of stealing Zeus’ light(e)ning. To clear himself of the false charge, he ha(s)d to meet Zeus, and he (starts) goes(ing) to the ancient Greek temple with two friends. (his one friend) One of his friends has the (duty that is he has to save) task of protecting Percy, and the other friend,is the  daughter of Athena, who he met in the camp where (has) there are many special half gods like Percy Jackson. While going to the temple to meet Zeus, they faced three devils and they defeated them. One (is) was Medusa. They (meet) faced her and they ha(ve)d some (little) trouble and they (repulsed) repelled her (with) back  with a mirror from his car like in the story of Medusa. Another one (is) was The Hydra. The Hydra (is)was a hound which ha(s)d three big heads. Percy and his friends went to the temple of Parthenon and got a pearl from a stone statue of Athena. There, they (meet) faced The Hydra, but they (can repulse) repelled The Hydra easily by using Medusa’s (sheared) severed head. The other part (one) is pleasur(e)able. Percy went to a casino and they took a drug and devoted (themselves) himself to pleasure. (But Percy finds himself???) and they (can) go out (from there). (And) When they went to hell, they (can) realized it (is) was Hades’ plot. They take away the light(e)ning from Hades and they meet Zeus.  They explain everything to Zeus,and return the lightening to him. Percy also meets his father, Poseidon who is so proud of his son (so much). So Percy and his friends (come) go back to camp and they keep training. Actually, Percy Jackson's story was an amazing fantasy for me, because i have read this kind of novel and  that’s why i like this novel,and especially, finally, when Percy met his father, i nearly cried. it impressed me and i think  I am going to read this book (for) many times.
