Kara had only just begun to enjoy her life as a mortal with David when they're pulled back suddenly into the world of the supernatural. The Legion has made an important discovery: a new Elemental child, whose whereabouts are unknown. Kara immediately prepares herself for battle, and comes face to face with the evil Seirs—a group of mortals devoted to the Netherworld.

What's worse, someone close to her is taken. Kara and her friends embark on another dangerous journey to seek out this child. But is this kid really an Elemental or something else entirely?
