I liked the plot, the read was pretty quick; one spice scene.
Two things really bugged me, the dialogue was set as during one time period but the characters would occasionally say more modern things. And the other was that the author was very, sometimes overly descriptive, on repeat. The character would think something, extrapolate about it, then in a paragraph or two have the same thought but worded very slightly differently. Kind of distracting.
While the demon could have been more demon-like, I did enjoy the story overall and would read another from this author.
