This book is very good. Jigsaw and Mila are kids so it is very interesting for kids. They act like kids I know. They have sleepovers and play with their friends just like regular kids. My favorite part is the ending because now I know the whole book. This book made me guess on every single page.
I recommend this book to students in grades two to four who love mysteries. Boys will really love it because it is a lot like Sherlock Holmes.
