Code of the Clans is the third Field Guide Book.
LIVE BY THE WARRIOR CODE...
The Warrior Clans have embraced the warrior code for as long as any living cat can remember. Now, for the first time, discover the secrets behind the code: What was the origin of the code? Which cats decreed the legendary laws? Which laws failed to become part of the code? All this and more will be revealed in CODE OF THE CLANS!
The cats on the cover are (from left to right) Blackstar, Firestar, Tallstar, and Leopardstar. In the backround you see many cat heads behind them, since the leaders are standing on a rock they may be on Greatrock and at a gathering which would explain the cats behind them.
