Ultra, I was told that my kids could not get library clearance into certain areas or even take AR tests on books without proven literacy. So, I just started my own library. My daughter memorized her AR log in and just started testing on her own books. Her teacher got weekly updates, and went and gave her clearance in the library to move beyond k-2... Which, by the way, has been useless. My daughter gets overwhelmed and brings home the biggest bunch of crud that I know she won't read, LOL.
She read a lot of fluff in k class. Rainbow magic fairy (same, AR is fifth grade in some of that, and its so fluffy), all the magic treehouse, all the junie b jones. She read harry potter (the first one) right before she turned 6. And yes, she stopped after goblets of fire. She was a little troubled by Cedric dying. So, I turned her on to percy Jackson, which is not as "deep" as the latter harry potter. But the first one is way fluffy compared to wrinkle in time in theme and content. By the way, your k class son might like the Charlie Bone books. They are like a gentle version of the Harry potter series, and they stay on the same level (fourth grade, ten points each) all eight books, where as potter grew up with the reader.
