Den of Liars (Caraval meets Kingdom of the Wicked in a sinfully indulgent heist romantasy) - Jessica S. Olson

A young thief attempts a daring casino heist during a high-stakes magical tournament and finds herself torn between two warring brothers. At the Liar's Den, secrets are power... Lola St. James is the world's best kept secret. When her father's loss in the magical Liar's Dice Tournament - a high-stakes competition where players are forced to gamble with their deepest secrets - made her a target, she was rescued by the Thief, the notorious leader of the Tentacles. Now, living under the pseudonym Astra, she is determined to prove herself and become a full-fledged Tentacle. But when a critical heist goes sideways, the only way forward is for Lola to compete in the Liar's Dice Tournament herself. Lola is confident in her ability to pull off the job, but the Thief's mysterious and powerful brother, the Liar, runs the game and he turns out to be more than she bargained for. As her attraction for him grows and illusions run wild, she will be forced to confront the secrets of her past, the truth of the brothers' history, and the lies she tells herself.
