1, little prince, this book is a book that people will read all their lives. It looks like a fairy tale, but it has different meanings as people get older. It will have a great influence on people's understanding of many things. The gift must be in the hope that this girl can remember you, so I think books that can be preserved for a long time and experienced for a long time will be better. You said that this girl is a little more mature than her peers, so I think she can see things other than fairy tales in this book, such as responsibility, such as keeping a childlike heart. There are many publishers of this book, including the blue-and-white cover of Shanghai translation (the picture style is very good and clean), the blue cover of Tianjin Education (with author introduction and audio books), or the gold cover of the world book (Chinese, English and French).

2. The Secret Love in Peach Blossom Garden, this book may be a little beyond the understanding of 13-year-old children, but it is indeed a very good script. At the age of thirteen, you can watch the dramatic conflicts in the script, which is very interesting; When I am old, I can see the persistence of love in the book, which is very touching; If you are older, you can see something in human nature. Generally speaking, this book is easy for girls of this age to accept as adults and will not be thrown away after reading it.

3. Jimmy's cartoon is also a good choice. It is clean, a little sad and has a kind of tension. If she can understand this feeling and likes the picture, then it is a good choice. I recommend The Forgotten Moon and Photo Album.

4. If this is a girl who likes literature and is more emotional, I also recommend Sanmao's works, such as The Story of the Sahara and The Crying Camel. There is a set of Sanmao classic works published by Contemporary World Publishing House, which is very good and comprehensive. At my age, this set of books has a great influence on me.

Finally, try not to buy the works of post-80s and post-90s writers. Their works are close to what children want now, but their functions are often somewhat negative. Since you say this girl looks like your sister, I think you still want her to be more optimistic and sunny. Therefore, after 80 s and 90 s, try not to send works that are too sentimental.

I hope it helps you.
