I'm of mixed opinion on this one - on one hand, I think the concept is great, and I really enjoyed and appreciated the variety and the multiple endings, but on the other I had quite a hard time getting into the prose here - there were some great lines here and there, but it felt as though it was a bit too hard to follow, with simple sentences being repeated multiple times and certain sentence structures showing up over and over again to the point of it taking me out of the experience (of note, the pattern of "not X, not Y, Z" repeated a lot). Worst of all, this muddies the writing and ends up affecting the characters - making it harder to figure out their personalities and what makes them stand out.

Even then, as this is the author's first work, I'm looking forwards to seeing how the prose can improve over time, and how the good ideas here can be improved on in the future to make for an overall stronger work.
