Rex Zero The Great Pretendor

the book I have been reading lately is Rex Zero The Great Pretender. I picked this book because when I read the back it sounded really good. the protagonist is  Rex the main character and the antagonist is Stew Leissier. the main conflict is when Rex and Stew start fighting and Stew breaks Rex's expensive school project which causes Rex to get really mad and he does something which is where I am now and if i said what he does that would spoil it. I don't completely know the theme yet and I am at the best part because the story is at the climax. I would rate this book a 4.75689231045 stars out of five.
