Hello everyone

Iam looking for this book called silver skulls portents Now i have found pdf files on annas archive and similiar sites but there is page number issue

Black Library and every site its listed on says it has 416 pages in phisical version but all pdfs i could find are 313 pages (103 pages short)

i read that differance in number could be bc "The print book uses the number of physical pages, while an eBook uses the retailer's approximation of what they figure is the page count" so i am really not sure
