The DARK CAROUSEL series is a heart-stopping mix of American Horror Story and the fantastical elements of Miss Peregrine's Home for Peculiar Children. The final terrifying story of The Dark Carousel series. As the day of Cassie's marriage to the centuries-old spirit, Balthazar, grows chillingly close, she finds a secret way to the high tower. The shadowy inhabitant of the tower has haunted her mind since her first day at the castle. In the tower, Cassie makes a shocking discovery, after which nothing can be the same. Before Cassie's last stand against the castle ends, she'll fight the serpent shadows that swoop in like spectres from across the frozen wastelands, and she'll face down Balthazar and the serpent empress herself. But her greatest fight will come from within.
