Marry the Enemy, Steal His Throne

Sera is killed by Prince Draven and reborn at sixteen. She breaks their blood bond publicly and allies with Kaelen, the sickly eldest prince. She exposes the mute wolf Lily's lies and traps Draven into revealing his ambition, leading the King to disinherit him. Draven's coup fails; he is imprisoned, and Sera takes her revenge. She and Kaelen rule together, have children, and find peace.
