I found I found a strange bug in the latest version of the book on iOS 13.1.3 (iPhone XS):
Chapters are not displayed correctly when you select them in the content menu of the Apple Books app. Also, many pages between chapters are missed. Had to download version 1.0 that works fine for me.
@dimon, are you reading the epub or pdf version in Books? I was able to get the full 2nd edition by going to the book site on my iPhone and selecting ePub for download and opened the file in Books. Try giving it another shot and let me know if you are still seeing issues and I can help troubleshoot further.
