Scarlett and her sister, Tella, have grown up on stories of the magician Legend and the magical game, Caraval. Stories that have helped them momentarily escape their grim existence with their abusive, controlling father. Now, weeks away from marrying a man she hasn't met, Scarlett receives an invitation to the palace, and Tella is determined to go, even if it means kidnapping her own sister to get there. Separated upon their arrival, Scarlet is driven by both the enticing candy-colored magic and her urge to find her sister. Along with the help of a handsome sailor, Scarlet explores the sinister estate of Legend and uncovers secrets about both her own past and the true dangers of Caraval.
