From John Rocco’s blog:
The cover for House of Hades, fourth installment of the Bestselling series, Heroes of Olympus by Rick Riordan has finally been revealed. Rick and I had a long discussion about this one, and when he sent me the manuscript I knew this cover would have to be the “Percabeth” cover. I can’t say much more about it, as you have to read it yourself, but please enjoy some art in the meantime. Below is the full cover that will wrap around the jacket, and also you can see the interior painting for a very special edition of the House of Hades that will be released sometime in October as well.
Awesome. Love seeing the full image used on the cover, and a very cool surprise to get to see that Special Edition interior painting early, too!
Also ends any speculation over exactly who is on the cover, as if there was any real doubt, and we now know for sure John actually gets to read the book himself (or part of it, at least) before deciding what image to choose for the cover. Not only talented, but super lucky! hah
