An interesting idea with good world building. Though none of the characters are saints, none of them are absolutely horrible either and this makes them all the more interesting.

I do kind of wished there'd been some warning about the three-way, blissfully faded-out, since I didn't need any more description than what was on page (TMI much?), but I would have liked to see more of the in world dynamics of the trio over a longer period of time. Though the arc is definitely finished in this particular story, I could see another story with Alim, Liam, and Sylvestra and them dealing with not only the fall out of their ended university careers, but also the university's getting wind of their plans for a more scholarly endeavor into not only "demonweave" but the demons themselves, and, of course, the poly-relationship they find themselves in. In fact, I would love to see how that develops!

(I was reminded of Tanya Huff's early fantasy book The Fire's Stone, with a similar set up with the characters)

This is an author who, if she keeps going, will improve with time.
By the by, the past tense of "grind" is "ground" not "grinded" (makes my teeth hurt reading that). ( )
