Violet's in her element. Cosplay at the ready, she can't wait to feel part of her favorite fandom: The Gallows Dance, a mega book and movie franchise that she and her friends know EVERY WORD of (canon and fanfic included).
But at Comic Con, a freak accident transports Violet and her friends into the story for real. And in just the first five minutes, they cause the death of the heroine, and get taken prisoner by the rebel group she was supposed to lead to victory.
It's up to Violet to take her place, and play out the plot the way it was written. But stories have a life of their own, and when you change the script in one place, the rest gets revised too...
