I just finished this book a few days ago and i LOVED it.
It's the summer of 1950. 11 year old Flavia De Luce loves chemistry (she's better than I am!!!). One night she wakes up and finds a body in the garden. Flavia should've been scared but she wasn't. Flavia does many things to solve the crime.
I loved this book because of the suspense. I couldn't put it down. Even when I was really tired, I forced myself to read more because it's such a great book. I was loving the book more and more with every sentence that I read. You should read it!
