Rebel Princess

The Princess Royal of a pacifist planet, whose people have spent a thousand years developing their powers of the mind, stages a personal rebellion, joining the space academy of a planet that has spent a millennium developing its military might. This odd pairing goes well until her senior year when her new "friends" turn on her. Only the swift action of an honorable huntership captain saves her from rape and possible medical experimentation.
As a very special prisoner of war, she spends four years in solitary confinement, where she dreams of her rescuer but has no idea she has inadvertently sparked a rebellion against the military planet's vast Empire. When the princess-in-disguise is finally freed and tossed into the middle of the Rebellion, she discovers there is a stark contrast between her fantasy version of the man who rescued her and the flesh and blood starship captain leading the rebellion.
She must also cope with his followers who fear her psychic powers, a fey younger brother who speaks only through illusions, royal parents with a strict belief in non-violence, and a fiancé who happens to be a sorcerer. It would appear the hope of toppling the Empire is a dim light at the end of a very long tunnel.
