So when Vera goes to sleep on the eve of her sixteenth birthday, she dreads the possibility of anything transpiring. A golden mirror appears in the sister's dream. Each girl admires their transformations, staring into a pair of newly acquired, violet eyes, marking their newfound magic. But the reflection reveals a startling truth-the other girl in the mirror is not them-not really. When they wake, they quickly forget about the girl as their bodies now hum with the lost magic.
