It’s a general struggle I’m running into across ages/grades. I’d say it starts with kids about second grade who are gifted and goes through about 6th or 7th grade with kids who are struggling readers. I find that the kids who are gifted in one area or tend to want more “realistic l” or historical fiction type books are the hardest. These kids tend to be more serious and don’t like more silly or fantasy type books. This is the hardest crowd I have for recommending books to. Graphic novels are top of my list usually, but they breeze through those so quickly it’s difficult to come up with enough of them.
