A Kiss of Embers by Sydney Winward

She’s the enemy. Loving her could turn his world to flames.

When Seraphina Nova’s younger sister is captured by her enemy, the Forest Fae, she will do everything in her power to get her back. Even if it means breaking into enemy territory, taking the chief’s heir as her prisoner, and using him to ensure her sister’s safe return.
Getting poisoned and literally dragged across the entire forest had never been on Bastien Dalena’s agenda, even if his captor had nice legs and beautiful wings. Despite the danger to his life, he knows one thing—Seraphina’s kiss is hot. It’s fire. It’s deadly. And he can’t help but want to feel the burn of her flames.
But as war reaches its peak between their people, an unexpected danger threatens their lives and forces them to fight together and build a fragile trust. Time is running short. He must form an alliance with Seraphina… Before their people destroy each other first.
