Sonya is an unassuming high school student who is invited on a journey to the galaxy's center by a classmate she hardly knows. They travel with counterparts from four other races and go through a spiritual awakening when they get to the center of everything. Along the way she falls in love with her classmate who dies on the way back. The middle part is about a problematic ambassadorship she has with Earth, and the end is a raucous tale of her role in saving the galaxy.
