Today a book cover has been revealed and that cover is;
The Iron Knight by Julie Kagawa! I have the first three novels but haven't read them yet. But, I love this cover. Not in the way most people would say it, I just love how it's different and darker than the other three. It's more masculine and can call a whole new audience to it. Plus, I love blue so yea. Also the model's eye color is really awesome and just pops out. All in all, one of the best covers I've seen this year.
I don't think there's a synopsis out for the novel yet, but it's set to come out in October so keep your eyes out for that! =D
