Ponies have reported mysterious happenings all over - sightings of strange creatures that leave destruction wherever they go. Still more are seeking help - a magic thief is on the loose. Not to mention the North seems to be acting especially strange. It falls to Sunny and her friends, new and old, to fix all of it. But she has started hearing voices in her head - voices that seem to have her worst interests at heart. She needs to find the strength to protect both her friends and what they stand for.
