This series is so fun! (Might be scary and intense for some kids). I am SO sad we have to wait until September for book 4.

I've listened to all the audiobooks. They used a new narrator on this one, and I was really scared it wasn't going to be great, but it was good. Maybe not as good as the original, but not distracting or anything. Sounded a little bit like Cary Elwes, which is never a bad thing.

One note on listening to the audiobooks: the codes aren't as fun. The narrator reads a big string of letters and you don't really get a good picture of how the codes work without looking at it all written out. Also, some of the codes are long so the narration of random-sounding letters can go on for quite a while.

But anyway, completely love this series. It's middle grade but not young middle grade. It's clever and fast paced the mysteries are so well done. This one had an ancient Knight's Templar curse & treasure hunt. Highly recommend.
