A/N: This is an idea for a story I have been playing with. Give it a read and tell me what you think.

Disclaimer: I do not own PJO or HoO.

However I do own the plot.

EDIT: I added in a brief history of WWI at the start of Ch 3. IT IS VERY BASIC so if you want to learn more I recommend checking out actual websites or books about the war.

April 17, 1918

Dear Annabeth,

I know it has been some time since I was able to write you and I do apologize. We have been hauled from town to town and stayed only one night in each new encampment. When we were finally given a days rest while it was decided where we would go I did write to you but that letter seems to have been lost while on the march.

While I say we were on the march there has actually been very little of that, instead they have continued to load us into large trucks and driven us across the French country side. I think you would have enjoyed the views and the scenery we have passed. I could not tell you the names of any important structures, should we have passed any, nor if they would have been of any real interest to you. For the life of me I still cannot understand what you see in one building or another.

We have arrived at our positions outside a small town in northern France but I cannot pronounce the name of it let alone spell it out on paper. This is to the dismay of a Frenchmen by the name of Nico di Angelo, from the French 167th that we have been placed with. They are to train us in what has been translated to 'proper battle techniques'. All they have trained us to do so far is to keep our heads inside the trenches and keep our socks dry if possible.

They are an odd group to say the least. They joke and laugh but much of their behavior is crude and best not described in the type of company this letter is addressed to. Nico seems like a good fellow but he is tended to be moody and bouts of dark behavior. He seems younger than us and I fear what fighting at such a young age has done to him.

I know you do not approve of my fighting in this war and I am sorry that my presence here brings you grief. Yet I feel that it is my duty and I must follow what my instincts tell me. Thank you for accepting my letters and continuing our correspondence. Yes, I did learn that from you.

You will be happy to hear Grover has been placed in command of one of the other squads of the 12th Co. 3rd Battalion, 5th Marines. He is, in fact, in the same platoon as I. Our company commander is a man by the name of Jason Grace. I wonder if he is of any relation to Thalia. I doubt it since he has said he grew up some where in California. He seems a good enough man, and while I do not know his age I believe him to be a year or two younger than me. What I know is that he is a career soldier and I am happy to have him as my commanding officer.

The Frenchmen are attempting to teach us more and get us some combat experience so I must go. I will try and write my mother soon but I hope that you will give her my love. Take care, Annabeth.

Your friend,

Percy

Annabeth sighed and pushed a few loose strands of her hair out of her way, attempting to corral them behind her ear. She looked over at the picture Percy had been sweet enough to take for her and his mother before he left. He was dressed in his uniform and, for once in his life, looked presentable. His hair was cut short at the sides but still had length at the top. He wore his hat, cover he had called it, and stood at attention. If not for his wicked grin you would have believed him a respectable sergeant of the United States Marine Corps.

She looked out the window of her father's New York apartment. They were calling this the Great War. That it would be the last war ever fought. Some where deep down Annabeth knew that was folly. That man would forever have petty squabbles and try and take from one another. She knew that Percy would not be home soon as everyone said. Annabeth sighed again before rereading the letter for the fifth time that day.

A/N: The idea for this is that Percy is a Marine fighting in World War I.

Please, please, please review and let me know what you think.

Thank you.
