When Phantoms — massive beasts made from nightmares and darkness — suddenly appeared and began terrorizing the world, four girls, the Effigies, each gained a unique power to control one of the classical elements: earth, air, fire, and water. Since then, four girls across the world have continually fought against the Phantoms, fulfilling their cosmic duty. And when one Effigy dies, another girl gains her power as a replacement.

But now, with technologies in place to protect the world's major cities from Phantom attacks, the Effigies have stopped defending humanity and, instead, have become international celebrities, with their heroic feats ranked, televised and talked about in online fandoms.

Until the day that New York City's protection against the Phantoms fails, a man seems to be able to control them by sheer force of will, and Maia, a high school student, unexpectedly becomes the Fire Effigy.

Now Maia has been thrown into battle with three girls who want nothing to do with one another. But with the first human villain that the girls have ever faced, and an army of Phantoms preparing for attack, there isn't much time for the Effigies to learn how to work together.

Can the girls take control of their destinies before the world is destroyed forever? (From Simon Pulse)
