Heart Shield has always been different from other ponies, and keeps mostly to himself. When he’s sent to Ponyville, he has to learn to adjust to his new life, and new friends; quickly getting into a routine of helping around the town.
Finding an injured Chrysalis in the Everfree Forest changes his life, and the lives of his friends, in ways he never would have imagined. Despite how the others view her, and despite the past he learns she and his friends share, Heart Shield has seen a different side of her and trusts her completely.
Has the Changeling Queen truly changed, or has she merely used the naïve pegasus while a wave of new, more powerful changelings threaten to destroy everything he and his friends know?
