The Unbreakable Code, by Jennifer Chambliss Bertman

I enjoyed this book immensely. There were several surprise twists and turns, and there was quite a bit of suspense, which is two of the elements needed to make a good story, and this book certainly was good! I would recommend this to anyone who likes suspense, mystery, and adventure. ~Madelynne, Age 9 North Buncombe Elementary First Reads Reviewer
