I bought this book for my 12-year-old daughter, and she loves it! The engaging way it teaches coding through secret messages is brilliant. She's already written a few codes and sent them to her friends. It’s a great way to mix learning with fun!

Damaged on arrival — not impressed
Unfortunately, the book arrived with a torn cover. I was really hoping to use it as a gift, but now I’m stuck with this damaged item. The content might be good, but with the way it came, I can’t even give it away to someone else. Major disappointment.

Interesting concept but a bit too basic
I had high hopes for this book, but I found it a bit too simplistic. It covers the basics well, but I was looking for something deeper. My 14-year-old was curious about coding, but he didn’t find it challenging enough. Still, it might work for a younger audience!
