For my final project, I created a Wakelet about The Best Mysteries for Ages 9-12. As a life-long mystery fan, I enjoyed immersing myself in the genre and I was impressed with the offerings for this age group. I personally read all of these books. In my reviews, I gave ratings for how scary the books are because children around this age have different sensitivity levels. Click on the link below to take a look.
