Apple Books

Stray thought that has been going through my head for a while now:

Considering:

• The complete redesign and rebrand of iBooks in iOS 12.
• The ability to mark any book, being it one you own or one you haven’t purchased yet, as want to read.
• The ability to add unowned books to collections in Apple Books.
• Apple’s focus on selling subscription services and increasing services revenue.

Wouldn’t Apple releasing Apple Books as a monthly subscription similar to Apple Music not be a logical step?
