Bloodsworn Lie

Seraphina, a pure-blood vampire girl, cut out half her immortal heart to save dying Prince Valerius, but her adopted sister Isabella stole the credit. When Isabella killed someone while drunk, the family forced Seraphina to take the blame, suffering seven years in Eclipse Prison. After release, she watched the impostor enjoy her life, with family and destined mate siding against her. In despair, she petitioned the Ancient Ancestors' High Council to erase her family identity and leave. Truth later emerged, the guilty were punished, but damage was irreversible. Seraphina never looked back, leaving Valerius and her family endless regret.
