"Heir to Mt. Fuji's spirit kingdom, Sora yearns to finally take on the sacred kami duties. But just as she confronts her parents to make a plea, a ghostly army invades the mountain. Barely escaping with her life, Sora follows her mother's last instructions to a heart-wrenching discovery: she is a human changeling, raised as a decoy while her parents' true daughter remained safe but unaware in modern-day Tokyo. Her powers were only borrowed, never her own. Now, with the world's natural cycles falling into chaos and the ghosts plotting an even more deadly assault, it falls on her to train the unprepared kami princess."--jacket.
