Raised among the white settlers, Touch the Sky knows nothing of his people's enemies, and when he returns to the tribe of his birth he discovers the history of his people. Original.
The Cheyenne series of historical westerns remains the only long-running westerns series in which I've read every volume. There were a total of 22 volumes. The author, Judd Cole, is someone I know, and he is a professional writer who writes both quickly and well. These books are told from the Cheyenne point of view, with a native American character who was raised by whites but returns to the Cheyenne as a young man. He is not completely accepted there either, and he finds many adventures on his way to being accepted by his people.
These are fast paced stories with a sympathetic hero and a lot of action and adventure. I highly recommend them all.
