First, come up with a unique and imaginative concept. It could be a strange new world, a special power, or an extraordinary character. For example, think of a world where people can communicate with plants. Then, create an interesting protagonist who will drive the story. Next, plan out a series of events or challenges that the character will face. This could be like trying to save the plant - talking world from a disease. Don't forget to add elements of wonder, like beautiful and strange landscapes or magical creatures.
To start writing a wonder novel, begin with inspiration. Look around you, in nature, in dreams, or in other stories. Maybe you saw a beautiful sunset and imagined a world where the sky is always on fire. Then, start building your setting. Describe it in detail, whether it's a floating island or a city under the sea. Develop your characters. Give them distinct personalities and motives. For instance, a character who is curious and wants to explore every corner of this new world. Outline the plot, making sure there are twists and turns that will keep the reader in awe.
One way to start writing a wonder novel is to focus on a 'what if' question. What if there was a library that contained every book that was ever lost? This could be the basis for your story. Then, you need to think about your main character. Are they a librarian trying to protect this library? Or a curious adventurer who stumbles upon it? Once you have your character, think about the journey they will take. Will they face challenges like magical guardians? As you write, use vivid language to bring the wonder of this world to life. Describe the smell of the old books in the library, the soft glow of the magic that surrounds it, etc.
