Sent to kill the last Dragon King, Seraphine Vale expects blood, vengeance, and the end of a war that has shaped her entire life. Instead, the moment her blade touches Kael Drakonar’s throat, an ancient mate bond awakens, binding her to the enemy she has been raised to hate. Kael is ruthless, broken, and dangerous, but beneath the legend of the monster lies a man betrayed by his own people and bound to a dying kingdom. As desire, magic, and old secrets pull them closer, Sera must decide whether the bond is a curse, a weapon, or the first true choice she has ever made. But the rebellion will not forgive betrayal. And if Sera chooses the Dragon King, she may have to burn down everything she once called home.
