I still really like this universe, even more now that they've introduced other pantheons than Christianity. I just don't like the characters much, which isn't a requirement for a book to be good and/or enjoyable, but I spent too much time being annoyed at their choices and their behavior. This problem is entirely mine though, and I'm sure other readers will get a kick out of it. One of my gripes with the first book was that Georgina is thousands of years old (literally) and still acts like that isn't the case. In the first book she seemed clueless about everything that was going on regarding the mystery, and while she's better in this one I still don't get why a person who works at a bookstore (and loves books, and has a lot knowledge) don't know some of these things (I realize that it is for plot purposes). She's just exasperating sometimes. I don't much care for Seth either, and Bastien, well, what an ass.
Another thing I didn't like was that there was too much relationship and to little mystery. The balance in the previous book was much more even, this one landed too heavy on the relationship side of things, which I'm also really not that into. Again, that's personal preference. The writing is fine, on par with the previous book, but none of the plot lines were all that interesting, I preferred the ambrosia one over the others, and that wasn't given a lot of attention.
