This was a more interesting, in a way, historical that I've read. . A sin eater- branded on the tongue with a collar around their neck. Their purpose is to hear the sins of others before they die. They should only talk to say the "Maker's prayer". Then they are to eat foods associated with the sins.
I had never heard of such a thing but they used to have them!
May is made a Sin Eater. She doesn't know why. She soon discovers a plot in the queen's kingdom and tried to find a way to expose it with the only tools she has.... Her ears.
This was a hard book to read because I didn't find most of it engaging. I didn't care for the slowness of the novel.
