The first two I nabbed from Summer Reads YA, because the blogger features some really great eye candy picks on a weekly basis. Although, I'd seen an ad for Dorothy Must Die on Goodreads several times and was intrigued by the cover and premise. I simply just like the second one. You can't see the tagline, but it reads, "off with their heads," so it was as much the art as it was the tag that got me. In the third cover, the red of her hair creates such a sharp contrast to the gray of the sky.
