Oh no! I just got an ebook I’d pre-ordered, and the file delivered is an ARC with “TK” in all the map spots.
I am cringing so hard in sympathy with this poor author.
My second book had a faulty pdf that went to the printer. Half of page 50 was missing. I glued a printed copy of that page in every book of the first printing.
(Thankfully, the first printing was just 50 copies.)
