I am looking for a fantasy novel which I read 3 years ago. I want to read it again, but the problem is I don't remember much about the novel. It was about a girl who gets letters from her grandfather (maybe?) and somehow enters into the world of stories or maybe turns into a fictional character, as if she was reading about herself in some story book. She is able to see the fictional characters (eg. Snow white, dwarfs, Cinderella) and normal people can't see her anymore.
Sophie's World, by Jostein Gaarder.
In this book Sophie is reading something that she's receiving in the mail. It contains messages to someone with Care of Sophie. At the end, it turns out that she is a character in a book and then she escapes with her teacher from the book. She meets the fantasy characters and the regular people can't see her anymore.
Sophie Amundsen (Sofie Amundsen in the Norwegian version) is a 14-year-old girl who lives in Norway in the year 1990.
The book begins with Sophie receiving two messages in her mailbox and a postcard addressed to Hilde Møller Knag. Afterwards, she receives a packet of papers, part of a course in philosophy.
Sophie, without the knowledge of her mother, becomes the student of an old philosopher, Alberto Knox. Alberto teaches her about the history of philosophy. She gets a substantive and understandable review from the Pre-Socratics to Jean-Paul Sartre. Along with the philosophy lessons, Sophie and Alberto try to outwit the mysterious Albert Knag, who appears to have God-like powers, which Alberto finds quite troubling.
Sophie and Alberto's entire world is revealed to be a literary construction by Albert Knag as a present for his daughter, Hilde, on her 15th birthday.
As Albert Knag continues to meddle with Sophie's life, Alberto helps her fight back by teaching her everything he knows about philosophy. Alberto manages to find a plan so that he and Sophie can finally escape Albert's imagination. The "trick" is performed on Midsummer's Eve, after Alberto informs Sophie's mother about everything.
When Sophie receives the letter for Hilde:
Sophie felt her pulse quicken a little as she saw who the postcard was addressed to: "Hilde Møller Knag, c/o Sophie Amundsen, 3 Clover Close..."
Dear Hilde, Happy 15th birthday! As I'm sure you'll understand, I want to give you a present that will help you grow. Forgive me for sending the card c/o Sophie. It was the easiest way. Love from Dad.
When Hilde reads this part:
Hilde read on and on. With surprise, she reads about Sophie Amundsen receiving a postcard from Lebanon. "Hilde Møller Knag, c/o Sophie Amundsen, 3 Clover Close..." (above text)
Meeting fantasy characters:
"I'm out of one of Grimm's Fairy Tales. That was nearly two hundred years ago. And where are you from?"
"We're out of a book on philosophy. I am the philosophy teacher and this is my student, Sophie."
