I’ve heard from a few different readers that there are problems with the Kindle edition of Absolute OpenBSD. It’s by no means every copy in every format, but there are enough problem reports that it needs investigating.
I’ve notified the publisher. They are investigating. When I have an update, I will post it.
Generally, when a Kindle file has a problem, remove it from your device. When the new version appears, you can re-download it from Amazon.
And this is the point where I mention that Absolute OpenBSD is O’Reilly’s Deal of the Day. If you want the ebook, you can get it for 50% off.
