Stain - A. G. Howard - Bog

After Lyra-a princess incapable of speech or sound-is cast out of her kingdom of daylight by her wicked aunt, a witch saves her life, steals her memories, and raises her in an enchanted forest . . . disguised as a boy known only as Stain. Meanwhile, in Lyra's rival kingdom, the prince of thorns and night is dying, and the only way for him to break his curse is to wed the princess of daylight-for she is his true equal.
