I also am having trouble with the download. Got the cover and the table of contents, but can’t get to a functional page.

Paid for the book and all I got was the book cover. Be careful with this one. Will try to reach out to support to see what’s going on?

I’m sure this is either the publisher’s or apple’s fault. But all I got for my $9.99 was a photo of the cover page. The actual book isn’t there. Scam. Do better, folks, honestly.
