She Returned as a Mystic

When Winter Sinclair was nine, a girl passing as the family's heiress accused her of something she had not done. Her mother took her to a cliff and pushed her off it. She lived. A master found her and took her away. Twelve years later she comes back to the city as a practitioner of metaphysics. She treats a billionaire, works cases no one else can solve, and gets known for it. Her mother has been having an affair. Her father acts in his own interest. The false heiress keeps up the act, and her brother goes along with whatever he is told. The Sinclairs move against Winter one at a time, and one at a time what each of them did is made public. The family turns on itself while Winter goes on taking cases.
