I loved The Mark of Hades and now The Mark of Eris and even though it's slightly a different style of writing because of the settings of the story, I AM ABSOLUTELY MAKING THIS MY FAVOURITE AS WELL. Just like @Isabelle Quilty said, the descriptions and idea of the story is amazing and even though it's the first chapter, it leaves a lot for my wandering mind to imagine and speculate what could happen next. Of course, I'm not entirely sure what will happen. Hence, on to the next chapter~
not gonna lie the concept and description you have is awesome, really tingled my brain-things. definitely keep going, I can totally see this when it's refined, edited, sleek. keep it up
