My son, who is baseball OBSESSED, picked up "Aaron Judge: Home Run Hero" for his AR reading this week. He practically inhaled it. He knows Judge's stats backward and forward, so this was right up his alley. It goes through Judge's life from when he was a kid, highlighting his adoption and then focusing on his rise through the minor leagues to becoming a star on the Yankees. If your kid is already a Judge fan, this is an easy win.
He said it was a pretty straightforward read. There weren't any tricky words or confusing sentences, which I appreciate. He liked seeing the pictures of Judge at different stages of his career, although he did say he wished there were more action shots from games. He finished it in one sitting, which is always a good sign. I skimmed through it afterward, and it seems well-written for its target audience. No fluff, just the facts about Aaron Judge. It wasn't overly detailed, so even kids who aren't hardcore baseball fans could probably still follow along.
The AR level is 4.8, and it's worth 0.5 points, which is good for a quick boost. He's in fifth grade, so the reading level was perfect. The word count is around 1800, which didn't feel overwhelming to him. He's definitely motivated by baseball, so that helped, but I think most kids in the 4th to 7th grade range who like sports biographies would be able to handle this.
Honestly, if your kid could care less about baseball, skip it. But if they know who Aaron Judge is and are even mildly interested, this is a good, quick read to encourage them. It's not super in-depth, but it gives a solid overview of his life and career. It was a much better choice than some of the other biographies he's picked, which have been dry and boring. This one kept his attention.
