Two Worlds One War
It has been a year since both the Chitauri attacked New York and since Camp Half Blood defeated Kronos. Camp runs normally with no more problems (well, no more life threatening ones anyway) and the Avengers live on their own, uniting whenever called upon. As life carries on, it seems that all it well and nothing could possibly go wrong.
That is, until Audrey showed up.
Audrey is a demigod, and a powerful one at that, but neither she or the Avengers know that. Audrey only knows that she is a demigod...an unclaimed demigod with a deep, dark secret. Soon after, an outside force begins to threaten the world again, and he knows exactly who Audrey is and how powerful she could be. Meanwhile at Camp Half Blood, the Oracle speaks of a demigod who could bring both the mortal and immortal world eternal peace, but another force, one that even the Oracle can't see, threatens to destroy both worlds and use this demigod to rule whatever remains. Now, Percy, Annabeth, and Grover must reunite again to go on one final quest: Find the demigod and protect her from this outside force.
As secrets begin to spill and Audrey's life begins to get even more complicated, the Avengers and Camp Half Blood must unite to protect their worlds from the oncoming war. The question is, what is it that Audrey seems so intent on hiding and why does she hide it from the people who are her friends?
