La sombra del caos (Los archivos de Ares, 3)

I'm Cleo, and if you thought saving the world once was complicated… imagine doing it twice. It all started with a small, insignificant detail: a trip through time to fix a problem. The result? Chaos, utter chaos. And that's not just a dramatic word that looks good in all caps (just ask the multiple versions of Ares and Leo trapped in it). While the Olympians are back to playing at being kings of the world, I'm doing what I do best: saving the world. But to do that, I have to go back to the beginning of it all, and… this time, sacrifice might be unavoidable.
