The reason you see output in irb is that irb shows you what
the last statement evaluated to, like this:

rasputnik@hypnotoad:~$ irb
irb(main):001:0> 1
=> 1
irb(main):002:0> quit


Object#inspect returns a string, but you aren't doing anything with it!
irb is showing you the value of book.inspect as usual, but the script
version is less verbose.

try

puts book.inspect

and you'll see output from the non-irb version.
