I set up our lit circles/book clubs throughout the year as genre studies so that all students read the same genre and we can get at specific standards and reading skills.
So we're doing fantasy next and my high level students (like your group mentioned here) will read either Tale of Despereaux level T or BFG level U.
And if it matters to you Stone Fox is level P (only gr 3) Shiloh level R (gr.4).
If you're trying to meet their needs and find levels which challenge them , Scholastic Book Wizard can help with that
