From the brief:
"The Charm is a book about the descendant of a rebel and a princess. There is magic, romance, and adventure; while the main characters try to reach safe rebel territory. There is a magical necklace on a golden chain. There are two charms on the chain. One is a red gemstone in the form of a heart and the other is a small pearl. The main girl character has the power to make people do as she commands with her words. When she does so puffs of red smoke come out of her mouth and the heart charm on the necklace glows."
