I loved this story about friendship and acceptance that includes an interesting mystery. The photography angle as a means to solve little mysteries - and eventually the big one - was clever. A more grown up Cam Jansen without the photographic memory.

I would say this is for older middle grade readers (10-14) because I found the solution to the mystery to be a little more mature than I would choose for an 8 or 9 year old. Of course, readers of any age come in a variety of maturity levels, but it is something I would keep in mind when recommending it to a reader.
