Shelby And the Shifting Rings: Book One in the Defender of Time Series

When orphaned Shelby Shodworth first arrived at Ms. Peabonnet's Academy for Girls, she knew it would be an adventure, but she never bargained for a mysterious stranger, a magical sword, and a curious star-shaped amulet that powers a hidden time machine. With the help of her brainy friend Molly MacPac, both girls stumble through a twisting labyrinth of questions. What Shelby doesn't realize is the answers she seeks will change her life--forever. Simultaneous.
