The Arcana Chronicles by Kresley Cole.
I just finished the first 2 books and have the 3rd preordered on Google Play (It'll be released on the 6th).
I really like them!

I'm absolutely dying to know who the girl that models as Evie is on the book covers... I've found the guy who is Jack, but there is absolutely NOTHING on the girl. She's absolutely gorgeous, though. The author even claims to not know who she is in spite of shooting the mini trailer of the books and the behind the scenes photo shoot for the 2nd one.
Anywho.
My sister loaned me "The Goldfinch". I have no idea what it's about, but her best friend pokes fun and says it's one of my sister's "smart people books". Lol
