Missionary to the Stars — Stephen A. Goodale

This is the fifth book in The Brethren Saga, a story that weaves the characters found in the first four books together with some new and surprising players. The New Federation is in a battle for their worlds with the despotic and evil leader of the Brethren High Council. Battles are won and lost throughout the Galaxy. Christopher Duncan is chosen as God's missionary to the Galaxy to bring the message of hope and redemption to all, while behind the scenes a new evil is growing stronger. The fate of the Galaxy hangs in the balance as Admiral Lambert rallies the free peoples of the Galaxy for one final battle against the evil that is the Brethren.
