A boy named Hart has a great life with his wonderful family until his parents get divorced. The divorce doesn't keep Hart away from his Dad. There are many kids out there in the same situation who can relate to this story. Hart and his Dad spend a lot of time together on trips to adventure parks. The main attraction to these amusement parks are the great roller coasters. They always write to each other and send each other pictures of coasters. Then one day something horrible happens. Hart's Mom meets a news channel wheatherman named Dub Dugan. Hart does not know what to do. All he thinks about is his Dad and what he would do if his Mom got married. Hart doesn't really like Dub because he is not brave and isn't good at riding coasters. If you want to find out more--like if Hart's Mom gets married or other interesting parts--then read this book. I would recommend this book for kids ages 8 to 12.
