Winter was sitting in the quietest area in Flourish and Blotts, and reading a letter that her sister had sent to her. It said:

Dear Win,
How is school so far, sis? I believe that you start studying tomorrow - correct me if I'm wrong. Make sure that you liven up to the name of Rhodesse. I was Prefect and Head Girl after all. I know that it must be hard that Summer has a slight illness, but she is getting better now and may be soon coming to join you. Try to bear it, dear.

I'm sending you a letter, hoping that it will reach you happy and with lot's of comfort. And, while I'm talking of comfort - you MUST check out a book called "Wise Words of Ravens" by Lucy Annington. Ok, what am I writing about, books? Anyway, I've got some fascinating news. I am officially Vice-Manager of Flourish & Blotts!! Yes, I have finally got hired for a job that I love - closer to books, the better. And, while I'm here, here is a personal message from Summer. She is weak to write but she tried.
Your loving sister,
Felicity

Winter, I'm hoping to go to Hogwarts soon. See you, my friend
Summer

Winter felt tears in her eyes as she patted the owl, Frost, who belonged to Felicity. She thought of her sister and felt a pang of home-sickness and sadness. She reached out for a random book and opened it, trying to "bear it" as Felicity said.
