Humiliation — Michael J. Findley

Book One in The Space Empire Trilogy --
What does a Prince of the Space Empire do when his father takes his toy away? Spend the summer in a Camp Meeting on Earth. Just what is a camp meeting? Open air and open water baffle men raised in tunnels and domes but the message of God's claim on their lives is even more disturbing. Alexander promised his family he'd come home alive, but Imperial SSTs targeting the Discovery might change his plans.
