Where Puppets Hide — P.J. Shepherd

Nine year old Luna Van Doran is sold to a Circus after a series of unfortunate events. She is immune to a life of neglect and pain, but nothing can prepare her for what happens once she enters. With a Circus built from the darkest minds the world has to offer, things aren't as magical as they might seem. From a crippled Ringleader to a demonic Puppeteer, Luna can trust nobody, even herself. With the power to raise an army, she must find a way to break free from the Circus before it's too late, and the world she knows is destroyed.
