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.)
