I struggled finding high Lexile level books with content appropriate for my gifted 7th grade students. This is the initial list I made when looking for books to recommend to my students. Following the list is a compilation of book reviews. I spent one class day having students use a Likert scale to rate how much they would want to read that book based on the book review. I took their responses and bought the most popular ones (I didn't mark these since your students' interests may be different from mine).
