Eva Braun did she live to tell the Berlin Bunker tale?

I hear a lot about Adolf Hitler,but what about Eva Braun there is almost nothing on this topic,and I feel that there is more to the story as there really is no known true story,but the fact that her body was not hers at the Berlin Bunker site,she would be 99 if alive today,Eva is the key to what really happened back in 1945.
