Del Rey posted the finished version of the Crucible cover on Facebook today. It hasn’t changed all that drastically since the first version revealed at SDCC. (Click on Luke over there to see the whole thing.) They’re also calling it for Summer 2013, as opposed to the original announcement of Spring, but until we get a more specific date I’m not going quibble over that.
The book is still by Troy Denning, and it’s still a hardcover. We’re pretty much guaranteed to hear more about it next week at Celebration.
