The Lady and the Order — Michelle L. Levigne

Bain and Lin meet up with Sister High Scholar Marnya, a member of the Order of Kilvordi - the Church scholars and scientists who brought civilization back from the destruction of the Downfall and took Humans back into space. Marnya needs their help on a very important mission: She needs to travel in disguise, to see if the conditions on the colony worlds match the reports that she receives. Plus, someone is trying to kill members of the Order, and Marnya is the most important target of all. Bain's dreams of having the power and resources to help the helpless come a little closer to reality as he learns from Marnya and her bodyguard, Jax.
