Gilded

Gilded is inspired by the story of Rumpelstiltskin, though it has many more details, twists and turns. The girl has the "gift" of lying and is a great storyteller. She is saved by a castle "ghost" that helps spin straw into gold. She befriends him and gives him more payments, up to the first born son (which he conceives in her.) The castle is inhabited by many ghosts and demons that she gets to know. She also learns from the people that a friendly ghost leaves gold for them.

The lord of the castle is evil to the extreme. He has no qualms killing or imprisoning others for his purposes. When the girl claims she can't spin straw to gold because she has a child in her, he wants to claim the baby as his own. He curses her to be bound to the castle. Through some investigation, she has also learned that the gold spinner was a prince who had his memory wiped and has also been cursed to remain in the castle. They hint at some plot to break the curses. And thus is the second book set up. The book itself is very dark with plenty of ghosts, but not very graphic.
