Farewell, Thunder Moon originally appeared in 1928 in Western Story Magazine. In this work, Thunder Moon is betrayed yet again and forced to flee his newly found home among those from whom he was abducted as a child. Returning to the plains that have been the scene of his greatest exploits, he finds the shadows of the encroaching whites lengthening on the lodges of his people.
Forced, in order to preserve his people, to make choices that they cannot understand, Thunder Moon must again confront his hereditary enemy, the Pawnees, as well as the oncoming whites. But soon Thunder Moon's greatest test draws nigh, and he must find where his heart truly lies.
