diary of the wimpy kid the last straw

the book was written in a way that it was written in a diary hand written. That made me read that book and the blurb and the front cover was interesting to read and see. the book was basiclly about a boy who can not think for his chirst mas suggestions(to improve)so he thinks to improve others since he thought he is perfect. the story goes on and in the end he was supposed to go to sprat union boot camp but his dad called it off.
