Two Halves of a World

This is a story about a different planet, a planet split into two halves that has been waiting to be whole again. The only way this can happen is through a marriage, a marriage fate designed billions of years ago, it's been in the stars waiting to happen. But an independent prince who is looking for something other than a princess is changing things, or perhaps stopping things from changing. The princess who is heartbroken by this and starts a raging war and the two halves of the world instead of growing closer are growing even further apart.
