Hard Face Moon — Nancy Oswald

Hides Inside is thirteen winters -- old enough to yearn to be a warrior. His brother, Standing Tall, has given him the first lesson, “A Cheyenne does not fight his own people.” Not even when other boys taunt him because he cannot speak.

On a dim night during the season of the hard face moon, Hides Inside witnesses the unprovoked attack on the Cheyenne that came to be known as the Sand Creek Massacre. His determination to join a warrior society is hardened, but will he follow Standing Tall in the ways of peace?
