In ColSecRebellion, Hill encourages racial harmony through the diversity of the heroes. Equality of the sexes is stressed by the active roles played by the girls, Heleth and Samella. The male characters are not stereotyped. Cord is a thoughtful hero who would rather resolve conflicts through reason than through fighting. The book does contain violence that younger readers may find disturbing. But Hill does not dwell on violence, and many readers will find his descriptions of battles merely realistic rather than excessive.
