A soldier's duty - Jean Johnson

Ia is a precog, blessed - or cursed - with visions of the future. She has witnessed the devastation of her home galaxy 300 years in the future, long after she is gone, but believes she can prevent it. Enlisting in the modern military of the Terran United Planets, Ia plans to rise through the ranks, meeting and influencing important people and building a reputation that will inspire others for the next three centuries. But she needs to be assigned to the right ship, the right company and the right place to earn that reputation honestly - all while keeping her psychic abilities hidden.
