Overall I like the main character, but she does have one major flaw..her inability to have any 'guy friends'. Even when she's dating there'll be some hot guys she'll label as a 'maybe'. To me that just seemed really shallow. She also can't stay single for at least 2 seconds, (well seconds when you're reading it, 2 days when you're her.) She'll say she still cares about this person A LOT, but then you'll see her kissing someone else or whatever, so that kinda makes you think that she really didn't give a thing about him in the first place. (Technically she does have 2 guy friends, but they're gay so does that count?) 
 (Not that this is a bad thing) the books also get you hooked. Even if you don't like the characters you'll want to find out what happens in the overall story. Plus, the writing does get better through the series, so don't worry about that aspect. In the first book it was like the authors had A.D.D. they couldn't stay on one topic for 3 seconds before jumping into something else. 
 There is a lot of prejudice you have to go through also. I think the authors based the only other religion in that world on a very weird version of Christianity. I think the authors just need to be careful about making a wrong impression when putting a specific group of persons into the story, and make sure that they actually do some research or something before they add them into the story. 
 They do mix pagan and Native American traditions in the rituals too. They call on dead ancestors and believe every plant has a some sort of spirit so they need to show respect to it. Personally I thought that was kind-of weird (no offense to people who believe that!) and it gave a different twist to the whole vampire thing. I guess they're very spiritual vampires...(???) 
 Despite all this, the story is actually interesting and it's a pretty quick read.
