well done. A typo i noticed in the first paragraph, you typed 'the mere thought of being to taste the fresh air again' I suggest you add the word able, 'of being able'. A bit more actions would be nice. Well done, and I look forward to reading this. I will read the next chapter as soon as I get free time to do so

Thank you for your suggestion. It is greatly appreciate and will definitely be taken into account for further chapters. I hope you will stick for that long, glad you enjoy it :)

I love the premise of your story, I felt hooked from the beginning. One thing I suggest for you is to add more actions per chapter. I felt like this chapter went by a little too fast. Maybe add a part where they get where the diver originated and the diver starts questioning him or like maybe the main character blacks out. You're the author though, so it's your call. Just try longer chapters
