The reading of this record is being re-voiced.

The audio archive for Sethaal: The Unkeeping has been temporarily withdrawn from circulation. The spoken record was struck from an earlier edition of the text; the text has since been corrected — every line, by hand — and the narration no longer matches the record it reads from.

Which is the in-world way of saying: the book was fully re-edited, so the audiobook is being re-recorded to match. The revised text is ready now — you can read the whole thing, free, while the new narration is made.
