La lunga pista rossa

Two mixed-race children, the offspring of the Apache Taza and a white woman, have vanished without a trace. Ken Parker follows a fragile trail of footprints, lies, and fear, until he discovers that the little ones have been sold to the dubious owner of a traveling zoo bound for Colorado. From that moment on, the journey becomes a long ride through the fiercest side of the Frontier: unscrupulous men, terrorized villages, Native grudges ready to explode, and a violence that seems to leave no room for mercy.
