The oldest, most devastating war of all time has found a way to resume, and is now inflicting itself on all of creation. Heaven and Hell are no longer the only settings for this terrible conflict. It began when the entire planet was shaken to its core. All of mankind lost the ability to move, helplessly watching in horror as the world crumbled around them. The phenomenon that would come to be known as the Wave brought about changes well beyond the scope of human understanding. Now we must survive the consequences. Angels and demons are among us; they are real. And they are bringing their war down upon us. A war in which we are insignificant; a war that we would not have thought possible and that will change our lives forever.
