I'm a newbie with Catalyst as well, so hopefully if I say anything too 
incorrect, others will chime in.  I think the best way to handle the 
book_id is simply to pass it via the URL.  So in your read_book 
controller, you'd have something like:
my ($self, $c, $book_id) = @_;
See the following page in the tutorial for passing arguments via the URL:

Hope that helps.
