This Isn't What It Looks Like
Pseudonymous Bosch
 The story starts off with Cass awakening somewhere unknown to her, in an unknown time (she later finds she is in fact in the Middle Ages), not knowing who she is, where she came from, or what she is doing. She sees a young boy stuck in a tree, and tries to rescue him, only to hear him repeatedly shouting the word "Goat!", evidently frightened. He runs down the road to his father, but neither of them even look at the girl. Confused, the girl walks up to a puddle, only to see that she has no reflection, realizing that she must be invisible, and that the boy was shouting "Ghost," not "Goat."
