I expect I'm horribly late to this, but two chapters of Shadow Scale, the sequel to Rachel Hartman's wonderful Seraphina, are available to read NOW:
The covers, the covers. I could die for those covers. They are stunning. I hadn't read a word about Seraphina before I saw that first cover on a bookshop table. I picked it up and bought it without reading the blurb, flicking through, or anything. The cover did it all.
The book was pretty great too.
