Stealing snow - D. M. Paige

Seventeen-year-old Snow lives within the walls of the Whittaker Institute, a high security mental hospital in upstate New York. Deep down, she knows she doesn't belong there, but she has no memory of life outside, except for the strangest dreams. And then a mysterious, handsome man, an orderly in the hospital, opens a door - and Snow knows that she has to leave

She finds herself in icy Algid, her true home, with witches, thieves, and a strangely alluring boy named Kai. As secret after secret is revealed, Snow discovers that she is on the run from a royal lineage she's destined to inherit, a father more powerful and ruthless than she could have imagined, and choices of the heart that could change everything. Heroine or villain, queen or broken girl, frozen heart or true love, Snow must choose her fate
A wonderfully icy fantastical romance, with a strong heroine choosing her own destiny, Danielle Paige's irresistibly page-turning Snow Queen is like Maleficent and Frozen all grown up.
