Cuauhtémoc [EPUB ebook] 
Descending Eagle

Book one; Descending Eagle, covers from his
birth, through his first few years as a child, his flight down to the birdman’s
school where he learns to fly; his encounters with other peoples: some
positive, some negative; his actions and reactions in each case.  It ends
up with his first battle with pirate raiders and his being sent to the City of
Emperors with messages for the Emperor; it stops as he leaves the
Commander.  Is continued in ‘Cuauhtemoc: Descent of the Sun
Priests.’
