To begin with, this story was about a girl going to a school carnival who figures out a mystery. When Cam Jansen goes to the game dime toss, no one ever seems to win it, even when their dime lands in the middle. Something else that was strange, two boys who looked like twins and two girls who seemed to be sisters were the only ones who ever won. Then, Cam went to check on her bike it was gone! Cam like to solve mysteries so this is another one for her to solve. She uses her photographic memory to find clues and figure out what is going on at the carnival.
In addition, I thought Cam Jansen was an interesting character. I thought she was interesting because she could remember so many things in her head. When I first read this book I felt excited for what was going to happen. I felt this way because Iíve never read a book like that before that included so many clues. I kept trying to figure out the ending while I was reading. This story reminded me of a time I had to solve a mystery. The book reminded me of that time because in the book it is all about a mystery and I like to be a detective like Cam Jansen.
In conclusion, this book is perfect for all boys and girls to read. If you like mysteries, you should definitely read it. Check for this book at your public library.
