There are a ton of good guides for getting kids interested in reading but Kathy Baxter is the queen! She is a dynamic speaker for librarians, teachers and parents and her books are must-reads if you are trying to inspire your pre-teen to read. She primarily focuses on using non-fictions to hook kids into books. Her book lists are terrific and updated often.
The American Library Association has great books lists. Here are their middle school picks from 2004.
National Council for Teachers of English has a nice page of book lists compiled by middle school teachers.
Here is a nice site for the Rhode Island Teen Book Award. It has book talks and discussion guides.
Here are the links to Beverly High School and Briscoe Middle School's summer reading information.
