Paranormalcy. Didn't like this book much, but this doesn't mean you won't like it. The girl works for some Paranormal agency that protects paranormal creatures and arrests rogue ones - something like that. She falls for one of the boys the agency is holding captive.

Personal Demons. One of my favorite series. The girl has some special power the satan and angels want. Satan sends one of his minions to tag her soul for heII and the angels send someone to protect her and some weird romance ensues. I can't wait for the 3rd book in the series.

Hush, Hush & Fallen but you've probably already read them since they're super popular. Hated Fallen, though.

The Darkest Powers Series by Kelley Armstrong!!!!

I swear thats my answer ever time someone asks this question, you would think more people would know about it by now. One day it will be a movie!

But seriously, its good and fits your description. Highly recommended.

Hunger Games. Read it. It is the best series I have ever read. Addicting book. Read.
