When writing fictional long form books, stories are normally structured. There are a number  of well know structures such as the three act structure. Can you provide me a list of story structures.
Sure, here are some common story structures used in long-form fiction writing:

   1. Three-Act Structure: This is one of the most commonly used structures in storytelling. The three acts are usually referred to as the Setup, Confrontation, and Resolution. The first act establishes the characters, setting, and conflict, the second act builds tension and conflict, and the third act brings the story to a resolution.

   2. Hero's Journey: This structure is based on the work of Joseph Campbell and involves the hero leaving their ordinary world, embarking on a journey filled with challenges and obstacles, and eventually returning home transformed. The structure typically involves 12 stages, including the Call to Adventure, Crossing the Threshold, Trials and Tribulations, and The Return.

   3. Save the Cat: This structure is based on the book "Save the Cat" by Blake Snyder and involves the hero being introduced in a sympathetic way early on, facing a number of obstacles, and then achieving a satisfying resolution.

   4. Freytag's Pyramid: This structure involves dividing the story into five parts: exposition, rising action, climax, falling action, and resolution. It is similar to the three-act structure but with more distinct stages.

   5. Seven-Point Story Structure: This structure involves seven key elements that must be present in a story: Hook, Plot Turn 1, Pinch Point 1, Midpoint, Pinch Point 2, Plot Turn 2, and Resolution. These elements help to keep the story moving forward and maintain momentum.

   6. Fichtean Curve: This structure involves dividing the story into five parts: exposition, rising action, climax, falling action, and denouement. It is similar to Freytag's Pyramid but with a focus on the emotional journey of the protagonist.

   7. In Medias Res: This structure involves starting the story in the middle of the action, rather than at the beginning. The reader is then taken back to the beginning of the story and led up to the opening scene.

These are just a few examples of the many different story structures that can be used in long-form fiction writing. Ultimately, the structure chosen will depend on the type of story being told and the author's personal preferences.
