Chadbourn himself seems to be a fan:
I’m very pleased with what John and my editor Lou Anders have achieved here. The covers really capture the awe and sense of scale I tried to place at the heart of the books.
As someone working on a novel that involves the same mythos as Chadbourn’s novels, I’m absolutely blown away by these and have to give Pyr a huge hand for getting cover art right. Fantastic.
