At last I have a brilliant new cover for Discord's Child, and I can't say loudly enough how thrilled I am with it. My own previous effort made the novel look amateurish.
The new design is the work of Katie Stewart at Magic Owl Design, and it's spot on. Despite being a pre-made, it features several important features of the story, and captures its atmosphere as if I'd given Katie a detailed brief. She was a joy to deal with, and I have no hesitation in recommending her services to anyone wanting to give their novel a boost.

Now all I have to do is make sure that the old cover is obliterated everywhere else it appeared!
