I am currently wrestling with the Amazon’s esoteric system in an effort to get Jake and the Dynamo published in the new edition. I breathed a sigh of relief when I saw the preview and realized that I and the artists had, in fact, got the dimensions correct. There is just the slightest error here, easy to repair—and props to you if you can spot it.
Looking at the interior, it appears also that Vellum, the software I’m using, behaves as advertised: I haven’t been through the whole thing, but so far, it appears that the formatting is correct with now weird artifacts or margins. I believe this new version will be even more attractive and readable than the original paperback publication, which I was already quite pleased with.
