ToH-Iberia is a flawed gem. It is an awesome book if used the right way. Yes, it skips big areas like Pelayo and the Basques, and it is "overseasoned" with Infernal flavoring. But there are also mant parts that are most excellent. Covenant of Barcelona for one. Mythic Visgothic history, the true story of Flambeau the Founder, and more. The bad parts are pretty aweful though, I do admit. Do some wikipedia research and you will do great (wikipedia is the ultimate gamer's supplament).
