Though her friends were disappointed, Twilight by her failed spell, Applejack by her apple theft, Rainbow Dash by her inability to gain cool fangs like Fluttershy’s, and Rarity by her unladylike dangling, nopony was really surprised.

Perplexed and virtually alone, Applebloom must plunge into a perilous rescue mission to find the lost citizens – a task that leads her into the most feared of places in all of Equestria: The Everfree Forest. But the forest is forever distorted – and for Applebloom, it’s safe to say that it isn't for the better.
