A young thief attempting a daring casino heist during a high-stakes tournament is torn between two warring brothers in Den of Liars, a thrilling YA fantasy romance by acclaimed author Jessica S. Olson.

Lola St. James is the world's best kept secret. When her father's loss in the 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. But the Thief's kindness came with a price: Lola's heart. In the years that followed, she and the Thief formed a bond like no other, able to feel each other's emotions because of their shared heart.

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 any heist, but the Thief's mysterious 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' shared history, and the lies she tells herself.
