I like the book more than the movie and would like to recommend it as it is longer than the movie. The book is also more exciting and thrilling to read as it contained more characters and information. I like chapter 20(I battle my Jerk Relative). The passage in this chapter I liked most is the one about Percy Jackson battling Ares, a god/immortal! He knew that immortals can't be destroyed, but he still fought Ares. From the title of this chapter, I like it already as I sensed how brave Percy Jackson really was, to call his relative (a god) jerk! He knew that he had little chances of winning, but he still challenged Ares. The fate of the whole world burdened his shoulders and he still could somehow "defeat" Ares using clever tactics! This also shows that his ADHD is helpful! That’s why I like this passage. (149 words)
