Wild Fire is Book 2 in the Charlotte Grace Series.
This book is much more supernatural based than book 1. Charlotte is caught up in the middle of the battle between exiles. That's not all she's caught up in. Oh no she's caught up in a love triangle between her very best friend turned lover Wesley and her exiled angel Olivier.
I'm one of those people that struggles with books and films that are hard to read. You know those ones that you really need to concentrate on so hard they give you a headache? I found this book a little like that, now that's not to mean I didn't like it at all because I did. And it didn't take me ages to read either because I read it in a day.
