I have every book.
I can lend them out.
Shadowclan:100
Thunderclan: 100
Riverclan: 102 +
Windclan: 99
Skyclan: 99 -
Tribe of Rushing Water: 100
I do say that 100 is about ten times too much. (We could also add StarClan, though technically StarClan is just made up of the other clans. I forget the Tribes' equivilant to StarClan, but they don't matter.)
