I really like the balance Giant Hunter’s Handbook strikes between mechanics and setting information. The new character options don’t overwhelm with their sheer quantity. Instead, they support the flavour of the setting. And the setting information provides you with a basic, but good understanding of how the people of Golarion interact with giants. After reading the book, I felt like I actually learned something about the world rather than just be presented with a bunch of character options that I would rapidly forget about. I wish the Player Companion books would reach this balance more often.
