Monster Princess of the Snowy Mountain

Valerie Beloff, a princess in exile, decides to take her own life on her 19th birthday. Abused by her own mother and exiled for her mother's crimes, she had to live in the freezing Makleroad palace by herself, and she somehow acquired the powers of an ancient monster—the power to freeze things. Hopeless, she seeks an escape in death... only to find herself before her cruel mother, yelling at her once again. Is she dead? Is she reliving a memory? When her mother strikes her, the throbbing pain lets her know that this is neither a dream nor a memory!
