The Dark Duke's Substitute Bride

Lilian, a poor young woman sold by her father to dark duke Leon, learns at the wedding that she only resembles his dead beloved Lyra. Humiliated by her stepsister, the household, and her husband, Lilian is eventually pushed into a sacrificial abyss by Leon in an attempt to restore Lyra's soul. The fall breaks the seal on Lilian's bloodline as heir to an ancient witch sovereign. Returning from the abyss, she no longer waits for rescue: she punishes her stepsister and father, challenges the ducal house, destroys the church that imprisoned Lyra, and confronts the ancient abyssal god before claiming the crown as the true ruler of night.
