Charmseekers: The Queen's Bracelet: Book 1 by Georgie Adams
When Charm became Queen of Karisma, the Silversmith made her a precious gift. A bracelet. On it are fastened 13 silver amulets, called 'charms' in honour of the new queen. The bracelet is magic with the power to control the forces of nature and keep everything in balance. As long as Queen Charm, and she alone, has possession of the bracelet all will be well. And so it was until Zorgan, the evil magician, stole the bracelet and scattered the charms far and wide. Then there was chaos!
Meanwhile, in our world (the 'Outworld' to Karismans), Sesame Brown is waiting to go shopping with her best friend Maddy. Little does she know she's about to be whisked away on the adventure of a lifetime. She's about to become a Charmseeker. Ses suddenly finds herself in a strange new land with castles and forests, princesses and magicians, the friendly tunganoras, Hob and Fig, and the less friendly gribblers. The race is on to find the charms and Sesame is determined to win.
