To accurately determine the mood implied by the story's setting in "Big Water" by Andrea Curtis, we would need to refer to specific elements and descriptions from the text. However, without the actual excerpt to analyze, I can't provide the precise mood.
That being said, if the setting includes elements such as natural beauty, calm water, and serene landscapes, it would likely be peaceful and relaxed. Conversely, if the setting features ominous weather, unsettling sounds, or a sense of danger, it might lean towards eerie and frightening.
If you can share the excerpt or key details from it, I can help assess the mood more accurately. Based on general assumptions, if the mood were either 'peaceful and relaxed' or 'eerie and frightening', these would be the two most likely descriptions.
