The main characters in this exciting funny book, The Fenway Foul-Up, are Mike Walsh and Kate Hopkins. They need to find a stolen lucky baseball bat for the all-star player on the Boston Red Sox. I loved this book. It was really well narrated and a great story. It was not boring or tiring to read. I loved the characters and the mystery itself. It was (for me) a fast read; I read it in one night. I would recommend this book to kids that like exciting fun mysteries. And you do not need to be a sports fan to enjoy it.
