I'll give it a 3.5. 
 This one was more of a romancy-UF, although in the end was more UF than romance. 
 I liked the main character. She was a bit clueless, but then she hadn't been exposed to the world of faeries, angels and demons for long, so it was understandable. That part felt pretty realistic - of course she's going to stumble when she's been almost purposefully kept in the dark. 
 There was a lot of interesting worldbuilding going on, but I felt like it needed to be fleshed out more. Lots of rules in this one and some things didn't quite click. 
 Some things bordered on the silly side - pervy miniature unicorn, for example, but it wasn't overdone. 
 I'll check out the next one.
