This book has 20 mysteries inside. Some are tricky, and some are quite easy. The characters are Marie, Noelle, Hailey, Brooke, Hope, Megan, Sage, Faith, and Rose. My favorite ones are: The Original Boston Brooke, and Love Letters. I recommend reading them with a friend or with friends. Each mysteries are just a page of two. I really like them because those mysteries can really happen to you, so you have to be a super sleuth!
