This is a trip of a modern fairy tale. I suppose I should have expected this, as Saint Death’s Daughter was an absolute trip of regular fantasy novel.
This is a shorter work, with goblins and fae, and travel between the worlds they inhabit, if you know the way. Desdemona finds the way after realizing the deal with the devil (er, Goblin king) her father has made to make himself (and her by extension) rich. Which sounds like a really standard fairy tale, but buckle up, because the author is going to bring you for a ride.
Read this for the world building, for the general atmosphere of this story. It’s delightful.
