The Princess Agenda: Complete Edition

What began as a serial novel, five shorter volumes, is now collected in a single volume, edited and modified to reflect the best version of this story. It began with a group of twelve young adults traveling to a remote campground to help their pastor restore it to working condition where it was revealed that they were not quite what they'd grown to believe. They are taken to another world where it's revealed one of them is the Princess to lead the forces of that planet, Valdria, against the hostile invaders, the Trae-Shan.
The group quickly learns the roles to which they'd been born and, with the revelation of the Princess's identity, join with the Valdrians to fend off the forces of the Trae-Shan to reveal the truth about them and the nature of the conflict.
