Helped keep out ADHD kid BUSY on road trips

We have a very ADHD son and keeping him off devices is a constant struggle. My wife picked this up for our last road trip, we were 30 minutes in and I could not believe he hadn't asked for an ipad yet, I turned around and he was DEEP into this good. Definitely recommend.

Very unique activity book

I got this for our kid because I had similar invisible ink puzzle books that I loved on road trips in the '90s. This one is a bit different than those in terms of the content inside and way the ink works with UV light, but it's a great book for curious kids. There are lots of little puzzles and mysteries to uncover using the pen and there's also room for creativity within the pages as well. I would love to see more products like this on the market with other content options.
