Tweak Book function somehow damages e-book
I have got a problem with the Tweak Book function.
Why I want to use it at all:
I own a Kindle Touch and want to buy some Kindle e-books of a publisher who a) very often uses fonts in his paper books that are at least for me too small for comfortable reading and b) does not seem to like e-books because not only he sells them for the same or even a higher price than the printed books but also he does format them terribly. Most of all the paragraphs are justified and have huge whitespaces between the words.
In short: Paper books: ouch, e-books: yuck.
So I played around a little with Calibre and discovered the Tweak Book function which "explodes" the AZW3 file into its components: HTML text, CSS style &c.
Since I know a bit about CSS and HTML I took a sample of a a Kindle book I want to buy and exploded it in Calibre. Then I added "text-align: left" to all paragraph styles of the text body, saved the changed CSS file and rebuild the sample.
When I opened it with the Kindle and with the Kindle app for Mac the paragraphs where de-justified like I had intended and for a moment I was happy. Then I noticed that the exploding/rebuilding routine had added a weird o> to the end of the file. But worse: When I clicked on "further informations about the book" or "buy book" at the end of the sample the Amazon web store did not recognize it anymore as a sample.
So my guess is if I process a full purchased e-book the way I did with the excerpt Amazon will not recognize that either. Which means that it doesn't get synched in the cloud. That would be as if I hadn't bought the book at Amazon at all.
Is that alteration a bug, did I do something wrong or is there a completely different way to tweak the appearance of books just a tiny bit while leaving everything else including the DRM intact? Or is this just a sample only behaviour?
I know that there is a Kindle tweak that allows to switch of justification. But neither does it work with the Kindle Touch nor do I want to jailbreak my Kindle.
Any help is much appreciated.
