Reborn, Lyra finds her sister Sera also reborn, again chasing Prince Aldric. In their past lives, Aldric tortured Lyra to death. Sera struck the final blow, and ultimately died with Cael, the useless second prince. This time, Lyra chooses Cael with a kiss, forming a blood bond. Her blood calms his unstable dragon curse. Ambushed by Sera, Lyra is stripped of scales and drained to feed Sera's dragon fetus. Cael feels her and rescues her. They find the moonlight flower, awaken Cael's pure-blood power, expose Aldric's blood-sacrifice plot, and defeat him. Sera also dies of blood vines backfire. Cael crowns Lyra sole queen. She rebuilds the deep sea, bears a dragon cub, and opens a new order.
