Legendary by Stephanie Garber

Book #2 of The Caraval series.

Donatella and Scarlett Dragna escaped their cruel father and made it out of Caraval alive, but the games aren’t over yet. What Scarlett doesn’t know is that, in order to gain their freedom, Tella made a deal with a mysterious stranger and now it’s time to pay.

Except what Tella owes is something that no one has ever been able to deliver: the true name of Caraval Master Legend. Tella’s only chance at uncovering Legend’s true identity is to enter the dangerous game of Caraval once more, and win. But what will she have to sacrifice to do that?
