I absolutely loved this. Strong, kick-butt heroine who is totally awesome, demons of various types, intriguing plot, awesome characters.
However, I'm not sure if I'll continue reading the series simply because I no longer really like reading series anymore, unless each book is standalone with different main characters. For this series, I'd love a book about Lucifer. I feel kinda bad for him.
Anyway, great read, full of action and romance and fighting.
