I had never heard about this book, so I used my trusted Google, and actually came back with a bunch of pretty good reviews, which confirm what kommesel said about it, starting with Greg Smith's on Slashdot and Amazon's User reviews (but don't forget to boycott Amazon).
In short it looks like a good book for people who already know other languages. It will infuriate the devout as often not choosing the Perl way, but as such it will not scare the newcomer. That's a valid angle for a book IMHO.
