Little original content, but definitely a worthwhile purchase,
This review is from: The Openbsd Pf Packet Filter Book (Paperback)
The basis for this book is the PF FAQ from the OpenBSD site, but edited, cross-referenced, and indexed, with some additional content. It provides the knowledge you'll need to get up and running with a PF firewall solution in most networks.
More advanced usage examples are the primary lacking in my opinion, and would make this a 5 star book.
Having the official documentation available in an easy to read, indexed format is well worth the purchase price. If you work with PF firewalls, buy this book. I also suggest taking a look at the two other PF books available, and consider purchasing all three, as I did. Each offers something the others do not.
I was surprised to not see any reviews here. For more detailed reviews than this, check out this book's page at reedmedia.net.
