I believe the prior chapter being referred to is the directly prior
chapter, titled "Getting Started", which shows a class implemented using
pointer semantics.

To be honest I'm a little surprised that pointer semantics are even
discussed; I've always regarded a pointer-semantics-pimpl as a bug
rather than intentional design. I suppose there could be occasions
where it could be useful for more abstract resources (eg. a database
connection) but doing it for a Book does not seem appropriate to me.
(Perhaps that's just my internal biases showing though.)
