Ravencross

Emily has always had only one goal in life: to study medicine to discover the disease that took away her mother and, perhaps, find a cure. Raised only with her father after that devastating loss, she always found comfort in her hometown, among books and the dream of a future that would lead her to save lives. But when James, her father, tells her that he has found a new love and wants to start over with a new family, Emily's world is shattered.
Forced to move to the luxurious home of her father's new partner, Cassandra Reynolds, Emily finds herself living with the latter's daughter, Grace, a girl as charming as she is enigmatic. There is no good blood flowing between them: Grace is hostile, distant, and seems to consider her an intruder. But Emily feels something strange not only in her, but in the whole house, where there is an atmosphere full of mystery, shadows that move through the night and looks that hide secrets.
Everything changes when he meets Damien, Grace's boyfriend. He is different from anyone I've ever known: magnetic, dangerous, wrapped in a dark aura that scares and attracts her at the same time. The more they try to avoid it, the more fate seems to want to intertwine them. And the closer she gets to him, the more Emily feels that the darkness that surrounds this family is not just metaphorical.
What was supposed to be a simple cohabitation becomes a spiral of disturbing revelations: Grace and her mother are not what they seem, and neither is Damien. Their secret is linked to blood, to eternity, to a world that Emily would never have believed possible. And as the line between love and danger thins, Emily will have to choose: stay anchored in her dreams or immerse herself in a love that could drag her into a dark destiny without return.
But the truth is more cruel than I can imagine. And the key to her past could be right in the blood that surrounds her.
