Hey everyone please help. I read a book years ago that was a different version of red riding hood. The story was that here was twin daughters to the kingdom and one was given or sacrificed to the "wolf" in the woods. But it wasn't a wolf it was a man. Within the woods is a kingdom housed in permanent fog. Something from the underworld was trying to reach through. And in the end both Red and the Wolf had some sort of magical powers imbued to them from the forest where they sprouted leaves antlers and bark upon their skin.

Please help this has been bugging me for a while now that I can't remember the title or author. Thanks in advance!
