Reeya Rai, and her best friend, Finlay Finnegan, are the children of archaeologists. This series follows them around the world as their parents work at various archaeology sites. The children travel to places like Madagascar, Turkey, and Paris, where they learn about a local historical artifact and use a relevant tool, like a spyglass, earthquake detector, and stethoscope, made with everyday materials to locate the item. Every book includes a short, illustrated introduction to the cast of characters. Reeya's family is from India, and the introduction includes a short description of Hindu culture and words. The books also contain instructions on how to build the invention used in each story along with a glossary and historical facts. The "Make Your Own" activity will need adult assistance. VERDICT Great for young readers who are ready to start reading on their own or still enjoy reading with an adult.
