A plot twist is a sudden, unexpected turn of events that changes the story's direction. Plot twists are often used to keep readers on their toes, to keep them guessing, and to add an element of suspense. Plot twists can occur at any point in the story, but they are most effective when they happen close to the end. This is because, by this point, readers have invested a lot of time in the story and are emotionally invested in the characters. A good plot twist will leave readers stunned, shocked, and eager to discover what happens next. There are two types of plot twists: those that are expected and those that are unexpected. Expected plot twists are often signaled by foreshadowing throughout the story. On the other hand, unexpected plot twists come out of left field and take readers by surprise. Both types of plot twists can be effective in their ways. An expected plot twist can satisfy readers because it confirms their suspicions and gives them a payoff for paying attention to all the little details. An unexpected plot twist can be even more impactful because it leaves readers reeling and desperate to discover what happens next.
