Best friends Emily and Aisha are thrilled when they're whisked away on a new series of adventures in the magical Enchanted Valley, where good Queen Aurora rules kindly over the unicorns and other magical creatures. The wicked unicorn Selena is up to her usual tricks, and she's stolen Ripplestripe's magical peace locket. Now friends from all across Enchanted Valley are falling out and even Emily and Aisha's friendship is in trouble. They must find the missing locket before friendships are broken for ever, so that the Crystal Ceremony can take place and preserve the magic of Enchanted Valley's healing crystals for another year.
