The Monstrous Duke's Adopted Daughter

Leslie Speràdo has lived her entire life in the shadow of her sister, Ellie, enduring years of starvation and abuse. In the Speràdo household, the second child exists only to be sacrificed in a dark ritual to pass on the family’s dormant shadow magic to the firstborn. However, when the flames of the altar fail to kill her, Leslie awakens the ancient power of the shadows herself. Realizing her biological family only seeks to exploit her new abilities, she makes a desperate gamble: she approaches Duchess Ariadne Salvatore, a woman feared across the empire as the 'Monster Duchess,' and asks to be adopted.

Contrary to their terrifying reputation, the Salvatore family is a bastion of loyalty and fierce protection. As Leslie transitions from a life of neglect to one of luxury and genuine affection, she must learn to navigate the complexities of high society and master her volatile magic. With the support of her new mother, her doting adoptive father Cyraine, and her protective older brothers Bethrion and Luenti, Leslie begins to heal from her traumatic past. The series beautifully balances these heartwarming family moments with the high-stakes political intrigue of the imperial court.
