If you want to run a Dragon-Blooded game, this is the book to have. The rules are pretty solid, and do a good job of making the Dragon-Blooded interesting while stil leaving them the weakest of the Exalted.
The first chapter on the Scarlet Dynasty is particularly good. The chapter on Outcastes is weaker, mainly because they are covering all the non-Realm Dragon-Blooded in less space. The Dragon-Blooded martial arts styles are some of the better styles in the game, even for non Dragon-Blooded Exalts.
I have a few quibbles in the rules: the mote-surcharge for out-of-Aspect Charms is a particular pain in play. Mostly, though, I am pleased with the content.
