When Princess Luna accidentally winds up in the human world and is unable to teleport back to Equestria, she fears what might happen to her. Miraculously, she is rescued by Hannah, a young girl who loves horses. She hides Luna in her bedroom until the princess can find a way home. Luna, who has only ever experienced the cruel side of humans, slowly begins to trust and love her new caretaker.

Luna faces an existential crisis when she discovers that in the human universe, she is known merely as a fictional character on a popular children’s television show. The princess becomes a celebrity overnight, but it isn’t long before Luna remembers that she is needed in Equestria, though she has become attached to Hannah.

Now, Luna must find a way home without being attacked by hordes of starry-eyed little girls and people who simply want to exploit her for their own selfish financial and personal reasons.
