I googled the isbn which confirmed it was the audiobook, then checked online store "Audible" which showed the same cover as I found for isbn & gave the publication date. Amazon must have been confused with Robert Galbraith being a pseudonym of J.K. Rowling. ;-)
The title says it's "Cuckoo's Calling" but the picture shows a boxed set of Harry Potter.
The publication date is 1999, which is way too long ago to be either one.
I am seeing other mentions of an audiobook of Cuckoo's Calling put out by Isis books but nothing concrete.
Any idea what to do in this case?
