May Night or the Drowned Maiden (Moonlit Tales of the Macabre: Small Bites Book 4)

This lovely (and nevertheless rather spooky) tale by Nikolai Gogol is rooted in Ukrainian lore. It starts quite ordinary - a young man is in love with a beautiful young girl, but other people and unforeseen circumstances stand in the way of their happiness. Quite unexpectedly, our young hero receives an offer of help from a very unlikely source.
