The Strangers by Margaret Peterson Haddix is the first book in the Greystone Secrets. Chess, Emma, and Finn Greystone always knew who they were, but things change when three other children with the same names and birth dates catch their attention.
This was an extremely interesting and fun read. I loved the characters, and the mystery that Margaret Peterson Haddix creates kept me turning the pages. I highly recommend this book to lovers of middle grade mystery.
