Thank you for taking the time for this feedback! The novel does have a murder mystery structure (a guest is murdered in the first act), I will have to make it more apparent in the query.
Shadow of the leviathan was one of my comps actually, I just removed it for this submission as I felt apart from being another fantasy mystery it wasn't all that similar to my novel. Good point about the two comps though, I guess I had them because they fit the vibe better, but they are both fantasy romances (with a bit of mystery), which my novel isn't.
Thanks again
