Perhaps worth checking your copy. There was a post on a Hymer group five days ago from someone whose book was missing pages 73 - 80 (southern Spain, Sicily, and part of Greece).
Pages 55 +56 were duplicated and some of the close up pages were missing.
However, no one else has commented, so wether this is a one off problem is unknown. There has not been any follow up by the poster as I write.
I am expecting an ACSI book later today, but it is a different version with Motorhome stopovers included.
