OK thanks. I did see those, and will take a closer look. My son really loves technology, and we spend a lot of time in the car, so I was trying to find some things to listen to while driving. He loves to read, but seems to stay hyper-focused (ADHD) on what he loves the most which is Percy Jackson/Greek Mythology or Minecraft (gah!). I've purchased some books for him, trying to broaden his interests, but so far, he's boycotting reading anything other than his 'favorites'. Was hoping to find something new to peak his interest by trying a different medium. I'll keep searching. Thanks.
