The Avengers. Earth's mightiest heroes. Ana Pierce is a S.H.I.E.L.D. communications and espionage specialist who's working closely with the Avengers. While working on the Tesseract, Ana is exposed to a dark and ancient power. This power has consumed every mortal it has bonded with, until her. To stop the mischievous Loki and his alien army from enslaving humanity, she releases this power with destruction and anger while gaining new allies and enemies from different worlds. She has to learn how to stop this foreign power from consuming her as this will not only threaten the world but the universe--or universes. If she fails, the Avengers have to face a dilemma: they must save either the universe or their friend who threatens it.
