Prince of Frogs. Curse of the Dark Kingdom, #1

A cursed prince. A reluctant assassin. One full moon before one of them dies. Prince Alaistar, the notoriously cold-blooded General, was left trapped on the western coast by the enchantment that befell the entire royal family. With a silver mask fused to his face, green-tinged skin, and a relentless magical pull toward the sea, most people see a monster. Evonna of Laerthar sees an opportunity. Desperate to rescue her missing brother, she agrees to a deadly bargain. Kill the cursed prince before the next full moon.
Or forfeit her own life instead. But getting close to Alaistar reveals a man far different than the ruthless villain feared across the Five Kingdoms. Beneath the mask is a lonely, touch-starved prince carrying the weight of his family's sins. And the more time Evonna spends with him, the more impossible her task becomes. Because if she fails, the bargain will kill her. And if she succeeds, she will destroy the only person who has ever truly seen her.
