Circus of the Dead Book Three

"Congratulations Callie, you're the puppet now."
What the devil does that mean? I've finally succeeded in doing away with Samuel, but I'm not really in charge of the island at all.
In fact the treachery runs deeper than I ever thought possible and if I'm not careful every soul on the island—both living and dead—will want to kill me for what I've done unless I discover who is really in charge.
Do I have the ability to overcome myself and do what I need to do or will I have to stand by and watch everyone I love die?
