Books where a main plot point is one of the main characters (who are girls/women; trans inclusive) turn into nonhuman, paranormal, and/or mythical entities. THIS MAY SPOIL THE END OF THE BOOK - read with discretion.

tried to look for a list like this and nothing came up. will add as I read more. Inspired by @breaklikeafish and @Invisiblelifeofkait's conversation in The Vegetarian reviews.
