Suns of Angels - Ghosts of Angels, #1

Some people affect the ones around them while others affect the world. Yet even the most powerful of these people are seldom no more than a blip in the history of the Universe. Fourteen-year-old Jessie is unique, as every one of her practical jokes, and every 'D' in algebra changes the course of history. Maybe it's because of her talent of seeing electricity in colors, or maybe that talent is just a sign of her destiny.
Jessie just wanted to bum a ride on the world's first anti-gravity spaceship on its maiden flight around the moon.  She gets more than she bargains for when they are attacked by a waiting Kan-ji fleet and end up stranded on the Kan-ji's 30-mile-long super ship. With the crew captured, it is up to Jessie to rescue her friends and escape. On her journey, a series of events transform her; a gift from the tree-like alien Chander fills her mind with knowledge of the Kan-ji and their technology.
A battle with the Kan-ji God, Loomius, leaves her reeling with his dark and ageless memories.  Now even with knowledge beyond her years, she knows she is still just a little girl trapped on a giant alien ship with her friends' lives depending on her.
