I'm glad you asked! The author, Charles Dickens, wrote the book because he felt that the true meaning of Christmas had been lost in the commercialism and materialism of the Victorian era. He wanted to remind people of the importance of generosity, kindness, and compassion, and to celebrate the spirit of Christmas. He also wanted to highlight the plight of the poor and disenfranchised, who were often forgotten in the holiday season. So, he wrote a story about a man who is visited by three ghosts, each representing a different aspect of the Christmas spirit.
