The Shadow Cipher by Laura Ruby

4.0

Amazing! Action packed adventure-mystery alternate present day that is a bit more technology based. In the early nineteenth century, the genius Morningstarr twins tranform NYC into an incredible city filled with amazing machines and awe-inspiring skyscrapers. Almost 60 years later they mysteriously disappear, leaving a puzzle called the York Cipher. It is believed that this puzzle will lead to a great treasure, but for over one-hundred years, no one has ever been able to solve it. However, twins Tess and Theo and their friend Jamie believe that solving solving the Old York Cipher is their only hope in saving the building where they live, an old Morningstarr building, from demolition. With less than 30 days until eviction, they set out determined to solve their the cypher.

Couldn't put it down! Can't wait for book 2! Recommended for 4th-6th grade. Fantastic read aloud.
