Janice Hardy unveiled the cover art for her her upcoming book, The Healing Wars: Book III: Darkfall. She writes:
I think this goes so well with the rest of the series. The artist in me likes the blue + red = purple way the trilogy covers work (blue Shifter, red Blue Fire, purple Darkfall) and the pouring hand captures a key moment in the story. I'm delighted with it and can't wait to see it on the shelves.Source: The Other Side of the Story
