Savannah Christopher is a very determined and driven girl. Even though she hits obstacles she overcomes them and gets better at basketball through her challenges. In Boost, by Kathy Mackel, Savvy plays 18u basketball as an eighth grader and gets extremely less playing time than she wants. Her sister, on the other hand, is a very unmotivated cheerleader, and selfish girl who only cares about herself. In the beginning of the cheer season, her coach told her she needed to lose weight to be the flyer on the team. Callie Christopher started taking pills that make her lose weight, making herself starve, and making herself sick. 

For someone like me who loves learning and watching sports, Boost, by Kathy Mackel was an amazing book. This book really pulled my attention in and had me at the edge of my seat throughout the whole book. I could connect to this book by relating to Savannah Christopher because she is super athletic and I am, too. I could also relate to her by being unmotivated at times and wanting to quit a sport. In all, I would recommend this book to 6th grade and up. Boost was an amazing book and I think that anyone who reads it would really like it just how I did. It wasn't a super complicated book and from the beginning of the book to end I loved it. The text is big and easy to read and clearly written. Overall, I think Boost was an amazing book and anyone who reads this review should read Boost.
