The Golden Eyed Raven. The Raven Warrior, #1

Anna grew up as the third daughter of a lower-class family and is assumed to live life like her mother; get married, get pregnant, and then died. This would be the easy path, but the brunette has a lot on her mind and won't allow herself to follow it. This is because, unbeknownst to everyone around her, Anna isn't just some teenager. But the reincarnation of a heiress named Morwenna, a woman who mysteriously vanished decades prior.
Long assumed dead, her name and legacy has been erased by her loved ones. One might think she'd be out for revenge, but Anna has accepted her new life and has a new goal. To utilize her intelligence and to become successful without a husband. She applies herself, meets the right people, and attends one of the nation's top magical academies to regain her lost power. However, snakes are all around her and Anna must steel herself to stay afloat when a massive wrench is thrown into her plans.
The disruption is that she's forced to work with a blonde healer named Edwin, who looks down on her for her status. The academy puts them together as a fake "academic power couple" for media play after numerous scandals. Drama ensues as the two rivals must band together, and work as Anna desperately hides her true identity from the rich boy.
