These books are amazing and tell you about background stories of mysterious cats that are in the tribes. Some stories will actually give you hints for the future of the tribes, for example: IF you've read History of the Five Tribes Peace Tribe's End, in the end when it says that Cry and Lucky refused to be in the tribes? Well, if you look closely it says that they became kittypets but was that really true? Think about it. Blood Tribe came from twoleg place. Could that mean that Cry and Lucky started Blood Tribe?
