What Evie from Paranormalcy Can Teach Us About Character Voice

Okay, so I've been rereading Paranormalcy to prepare myself for Endlessly. (I tried to read it and I couldn't remember any of the plot, lol.)

And anyway, one thing I've always loved about Evie is that she has a great voice. Here are some things I love about her:

1. She has flaws that repulse even her. (Can't go into what, spoiler.)
2. She feels hurt and lonely at times. For example, she often feels hurt that her guardian, Raquel, isn't her real mom, and when Raquel reminds Evie that she is an employee, it hurts her feelings. 
3. Despite those things, she is happy, and blubbly; something I love. She chooses to be happy and not negative. 
4. The best things about Evie are the little details, like her love of pink, her pink-and-rimestone taser, the fact that she has a favorite TV show(Easton Heights.), how she says "bleep" in place of cuss words. Those little things make her feel so real and three dimensional to me. I mean, how do you not love a character who fangirls at lockers?
5. Just seeing Evie going about her routine is great--like when she meets with her tutor Charlotte, and hasn't done her homework(And writes in Spanish "I am dead meat." :D), to her going on a bag-and-tag (aka her job) and going to talk with her best friend when she gets back, and then chill after that by watching Easton Heights. White took the time to get to know her MC that is for sure. 

So what are some things that we can take out of Evie?
