This is a curtain fic/fairy tale with Dean as a flower fairy and Castiel as the injured bat sprite that he takes into his home. No sex just an abundance of cute.
While the book was stunning, even without true romance, I can't give it five stars.
The last chapter ruined it for me. Not because how it ended but the way it ended. While I cheered for the MCs, I could not connect with that reality.
Don't want to say anything else for the fear of spoilers, I already gave away too much.
@Monica - thank you, my friend, for the amazing rec and gift :) *hugs*
