Dearest Prim,
Months have passed since I left you at the train station with Mom and Gale. You were so brave to stand tall as they took me away to the Quarter Quell. You are growing up, my little duck, and I wish I could have the chance to see you grow into a strong, loving, beautiful woman, the kind of woman any sister would be proud to have, but I'm afraid you and I will have to remember each other the way that we were in the moment at the train station.
I've stumbled upon a magical place. To make a long, confusing story short, there was an entrance to this new place hidden in the depths of the Quarter Quell arena. Prim, I'm happier than I've ever been. I met Cedric not long after my arrival. Cedric is tall, dark, handsome, and the kindest, gentlest soul I've met besides yourself. I'm sure you'd like him.
And, he wishes to let you know that he will love and cherish me for the rest of my life.
Cedric wrote that last part himself. Prim, I am writing this final letter with tears in my eyes knowing I won't ever see your smiling face again. I hope you will understand my decision. I hope you will find someone or something that gives you the same happiness as Cedric brings to me.
I love you, Primrose.
Your sister, forever and always,
Katniss

Katniss hugged Finnick for the last time. After the embrace, she handed him the wax sealed letter to Prim.
"When will you leave?" she asked.
"Tomorrow morning, I hope."
"Well then...I...uh..."
Finnick touched her on the shoulder and shook his head. With heavy eyes and a soft smile, he gave her a last look then walked towards the lake and the Durmstrang ship. She watched until he disappeared in the distance.
