The Lost Journal of Erika Traynor — Ceara Comeau

No one really knows how the war began or why. It was just always going on, at least it had been that way for three hundred years. Most people were convinced that it was the way of life and nothing could change. Except for cousins John and Riley who believed the war was not what it seemed. Unfortunately, they had no way to prove it. With a lot of searching, they came across an unusual treasure. It was a long fogotten journal whose secrets revealed the cause and end to a senseless war.
