In a world torn between ice and fire, Seraphine, a powerless “scaleless” woman, is forced to take her half-sister Vesper’s place and marry Kael, the ruthless Dragon Lord of the Ashcrown Clan. Everyone fears Kael—but he knows a secret no one else does. Seraphine is the mysterious girl who saved his life ten years ago. And now, he’ll risk everything to protect her. Then Seraphine awakens the long-lost Frostveil bloodline and is rescued by her birth mother, Isolde, and a mysterious tribe. As she masters the ancient power of Dragon Tongue, she discovers the shocking truth behind her bloodline—and the war that has torn their people apart. But when Kael is captured, Seraphine returns to the battlefield to save the man she was once forced to marry. Together, they face the ruthless usurper Theron, expose a conspiracy buried for years, and challenge the hatred that has fueled generations of bloodshed. But can their love survive the final battle? On the edge of a sea cliff, Seraphine and Kael make an eternal vow—and ignite a new era where dragons and scaleless humans can finally live side by side.
