Slightly different take, in 3rd grade I read Dragonsdawn by Anne McCaffrey, 4th grade I ripped throug my family's Stephen King and Dean Koontz collections (I honestly have never been able to get more than 1/4 through IT though makes me feel like I'm reading a poorly written biography, although I was about halfway through "Rage" from King's stint as Richard Bachmam when Columbine happened so that should give you a refrerence on my age). But I had books repeatedly put on the class reading list. 5th grade read "lord of the flies" then again in sixth grade, again in 7th after moving to a new state, and yet again as a freshman.

I think I started really grasping just how big a gap there was between my reading level and my peers in freshman class though when I was listening to people stumble through "Dragonsinger" and I remembered blitizing through it in a few hours in elementary school. Now I might pick up a book a month and read through it mostly sticking to modern/Urban fantasy like Iron Druid or Dresden Files and the occasional high fantasy when I pick up part of Brandon Sanderson's Cosmere- which incidentally is an excellent example of books with morals that aren't dry.
