First thing, I love to applaud you with the concept. For me, it's new, unusual and I never heard of it before. The thing about sci-fictions today are the ideas seemed identical so reading your novel was refreshing to me. Another is I love how you already put distinctive traits for each character you presented which makes us readers easier to differentiate with them and note them individually. And what I like the most is how you lay the events perfectly that lead to string age. It helped put depth, add mystery and stir my curiosity. What I'd kindly suggest is apply flashback rather than descriptive explanation of the past(though, it's up to you especially if that's just your style) because I personally think it has more feels. Nonetheless, I had no problem with grammar or mechanics because I honestly didn't see errors on those. Ultimately, kudos! I really admire sci-fi writers because I believe they had the hardest time. Anyway, keep the fire in you burning!
