39 Clues: Unstoppable (series: 4 of 4)
I have a masters degree and worked with at risk teens for years.
The series of books/audiobooks, The 39 Clues (all missions), is outstanding. It has suspense, ancient to modern history, geography and ironic, interesting symbolism for kids, teens and adults. Well done, authors!! Bravo to the excellent narrator - he’s the best I have ever heard; (and I’ve listened to thousands of hours of audiobook and documentary narration - greater than Animal Planet because the talented, precise accents of each character is a huge plus!) Amazing and exciting way to help us all learn, or remember.
