Prince of Swords by Elise Kova

Welcome back to Arcana Academy. Tarot magic, forbidden desire, battle, and betrayal collide for the power to change the world in the thrilling second book of this New York Times bestselling fantasy romance series.

I am terrified. Yet my heart skips a beat. This man might be a monster, but he is my monster.
Clara Graysword is Oricalis’s most wanted. Hunted and cornered, not even her mastery of tarot can save her this time . . . until the mysterious Worldkeepers appear. This secretive order may hold the key to changing Clara’s fate. If she dares to trust them.

But the most dangerous alliance of all is one she’s already deeply ensnared within: Prince Kaelis.
Kaelis, second-born prince of Oricalis and headmaster of Arcana Academy, is the one man she can’t escape—maybe she doesn’t want to escape. Ruthless, dangerous, and bound to Clara by destiny and desire, Kaelis tests her heart as much as her loyalty. Together, they grow closer to the most powerful secrets of the tarot . . . and to the truths they both hide that could destroy the passion that they no longer deny.

Hidden in plain sight within Arcana Academy, Clara walks the dagger’s edge. Revelations about Oricalis threaten everything she thought she knew, and every choice she makes is the difference between salvation and ruin.

To change the world, Clara must risk everything—her power, her beliefs, and her heart.
