One of the awesome things I get to do is tutor a fourth grade student each week. I am helping her develop her reading skills and right now she’s reading Harry Potter. She loves it. In about a month we will wrap up our tutoring for the year and I’d like to give her a book to start her summer reading. I’m looking for recommendations. While she is currently reading the fourth book, her family owns all the HP books, so I’d like to get her something else. She loves mystery, adventure, humor, and historical fiction about American slavery. She’s at a Lexicon level of 890. Any suggestions?
