I suspect it's this one:

https://www.amazon.co.uk/dp/B07DF9CLGB/

Which is the Penguin Classics Kindle edition.

Much appreciated - thank you. The ASIN is B07DF9CLGB.

Yes, it is. Thanks, Paul.

The "house full of random swimming birds" more often needs their ebooks fixed than any others I buy, inc SP titles.

fully zoomed in, on dark pages in 2-page view (so i can better see the white line), i cant tell its there, both with the book directly downloaded on the kindle and the kfx downloaded on pc and copied there with calibre.

it only really becomes noticeable when converted from the pdf based kfx to epub (or cbz). my guess is that that sub pixel line gets "amplified" by whatever pdf conversion method this plugin uses (maybe a different cropping box than "artbox" or "cropbox" or it just behaves differently than mutool).

another look zoomed in 6400% into the pdf page, see the tiny white line at the right and bottom (which are likely part of the original, its just that they get more pronounced when converted to epub/cbz):

Jumping to that ASIN showed a possible source of the problem: It's a UK-origin book. Which means that in the printed edition, the US page sizes (and often ledding) are different — and due to the flightless bird's process, that's going to present problems with doing a conversion-from-a-conversion. My suspicion, which I can't prove but is consistent with another publisher's problems, is that their internal stylesheets accessed from their typesetting programs have hardcoded metric measurements that get converted to hardcoded "English" measurements for US editions (and ebooks "fulfilled to the US"), even though not visible, and then things go haywire at random deep in the decimal places...

It’s a British book. I’m in the UK. I bought the book from Amazon UK. I don’t understand why anything involving US measurements would be involved? I collect the Penguin Classics series and over the years I’ve bought well over a hundred books in the range. I’ve never had any issue with one prior to this.
