My five year old son loves these stories, and I enjoy listening to them as well. The cameraderie among the siblings is refreshing and it is nice how resourceful the kids are. Each of the stories has an element of mystery to them, which keeps you interested. (My three year old, however, starts to get antsy with these stories, because they are so lengthy - we have to take Dr. Seuss and Nate the Great breaks for him!)
My son started listening to the Nate the Great audiobooks a few months back and quickly became bored with them. He loves that these A to Z Mysteries have a more involved story line and a bit more suited for "big kids". The language is appropriate (don't have to worry about hearing "shut up" or "stupid") and I like that the kids in the story are resourceful. The only complaint I have is that most of the stories I have listened to so far are about finding a thief...would be more interesting if they switched up the mystery a bit, but that's just me.
I purchased this audible book for my 8,6, and 4 year old grandchildren and I to listen to on a long trip. They loved it! I had to keep checking to see if they were asleep because they were so quiet. I learned just how interested they were when I turned the book off during heavy traffic, so I could concentrate more on my driving. They began playing, quarreling, and doing all the things they normally would do had we not been listening to the book. As soon as we returned to the car after a stop, they were all telling me to turn their book back on.
The reader did a awesome job of changing voices with the characters. She really made it seem as if we were seeing the performance in person with lots of different actors.
Although the book was originally written for young teens or pre-teens even before I was born, it was still enjoyable for an old lady of 60 like me as well as my grandchildren. I would definitely recommend it to others.
