suggestions?

here is part of my book review so far. what do you think? any suggestions to make it better?
Mary Lou is 13 yrs old. She writes a lot in her journal- she’s filled up six little notebooks! She lives with her mother, father, sister Maggie, brothers Dennis, Doug and Tommy. Maggie is the oldest of the 5 siblings at the age of 17. Dennis is a troublemaker, throwing eggs and apples at houses, like their neighbor, Mrs.Furtz. Doug, a.k.a. Dougie, is a quiet little 8 yr old who calls himself “the poor little slob”. Tommy, a 4 yr old baby, according to Mary Lou, “We (the family) think he’s cute as anything, so he gets away with murder. He’s the messiest eater you’ve ever seen.” It can put the image of a little innocent baby with spaghetti strewn over his head and milk dribbling down his chin while an abundance of food is on the plate, table, floor and the baby himself. The book is about how Carl Ray, one of Mary Lou’s many cousins, comes to Easton and gives Mary Lou’s summer vacation a twist she won’t ever forget. Carl Ray is a quiet fellow who sneaks up for you, and never cleans up anything-his bed, his room, nothing! In addition, he has a humongous appetite! One interesting parting this book was when Carl Ray spills his whole story. It took him a long time to say it, and it kept me in suspense. Mary Lou was growing impatient, “’I DO! I DO! I DO!’ I stopped. I counted to twenty. I breathed deeply.” And also, “’Very good. Very good indeed, Carl Ray. Thank you for telling me all this.’ Sometimes, when you talk with Carl Ray for a while, you begin to lose your marbles and talk like an idiot.”
