Then, guests mysteriously fall ill and a dangerous fog appears, trapping everyone. Someone with a lot of magic is causing trouble. The one person who can help is the fairy Moonbeam, and Annie's immunity to magic makes her the only person able to reach her. With Liam in tow, Annie embarks on a wild adventure beyond the castle walls. Along the way, she'll run into some familiar friends... and some dangerous new foes. Will Annie be able to reach Moonbeam in time to turn everything around?
