假如你是高中生李越，请用英语给你的一位朋友写一封100-120个词的信。信中应包括以下内容：

My dear friend,

My favorite book is Harry Potter, which is a series of books written by JK Rowling. It is not only about magic and strange creatures, but also about the real world. By reading the book, you can learn that the most important lesson for us is about real life, friendship and how to be brave. Besides, you can also learn about the power of love. It teaches us that if we want to be happy and live a good life, it is not enough to be strong in heart and mind; we must also believe in ourselves and help others. What’s more, we should know who we are if we want to succeed in the world. I think Harry Porter is really a book worth reading.

Yours sincerely，

Li Yue
