Apache Devil

Sequel to The War Chief
From inside cover of Ballantine first edition:
Shoz-Dijiji, the Black Bear... a white man who believed himself to be a full blooded Apache, and who had dedicated his life to a feud against the treacherous white eyes who had invaded his country and destroyed his family...
To the pony soldiers and to white travellers he became known as the Apache Devil, a pitiless scourge who swept in, killed, took his vengeance, and slipped away without a trace. Thus Shoz-Dijiji, the adopted son of Geronimo, was honored in his tribe.
And even among his sworn enemies there were those who called him just, and a friend. One of these was a woman--who loved Sho-Dijiji. But she was white--an impossible obstacle to the racial pride of an Apache warrior.
So Sho-Dijiji continued to live his life of hate and loyalty and love, of running fights, of massacre and torture; until at last even the tribe of Geronimo signed a peace treaty with the white men--and Sho-Dijiji learned that the woman he loved had been stolen by renegade white outlaws. Then Sho-Dijiji hunted as he had never hunted before.
