my number four is an author that mainly writes for the age of 9- 12. but im TOTALLY in love with his books, they are funny, and exciting, and they are so INTRESTING! i always learn new thing, about myths, which i think is awesome, because his books always make me intrested in those kind of things. if you asked me like 3 years ago what i thought about Pallas Athena, i would go like "what, the city?" hehe, but i really think you should check out his books!
he is BTW the author of Percy Jackson and the lightening thief! (yes the movie is based on the book, and the 2nd film is coming up next year! im sooo excited!)
