About This Book
Reach for this book when your child is constantly seeking puzzles to solve or needs a boost in logical confidence. It is a perfect fit for the 'maker' kid who thrives on hands-on learning and wants to see how math and patterns apply to the real world. The story follows twelve-year-old Alvin and his friend Shoie as they stumble upon a mystery involving hidden treasure and a retired spy. Unlike many modern thrillers, this classic focuses heavily on the 'how' of the mystery, teaching readers actual cryptographic techniques while they read. It celebrates intellectual curiosity and the satisfaction of a job well done. Appropriate for middle-grade readers, it offers a wholesome but high-stakes adventure that encourages perseverance and teamwork. You will love seeing your child grab a pencil and paper to decode the puzzles alongside the protagonists.
