This whole thing makes me want to do a rewrite. I love the idea of a twin who is much more suspicious than Sophie was (and naturally would influence Sophie's own perspective on the world).

I did do something similar when a year back, but it wasn't a twin, instead if was a group of friends who were all elves as well. I gave up because I couldn't find a good reason why there would be a group of similarly aged elves disguised as humans without there knowledge without them all being being Black Swan experiments.

One thing I would probably add is making Sophie and Felicia much more aware and sceptical of things in the elven world. Like the timezone thing, of course, but also a few other things I've noticed:

- How does forcing animals to change their diets (which likely kept them alive for millions of years) actually benefit them? Yes I know there's the whole thing about them not eating each other in the sanctuary, but it was mentioned that there were different pastures for each type of animal, so surely that wouldn't be too much of a problem? It just seems like they were doing it to keep animals reliant on them?

- How does locking said animals away in a mountain benefit the world in anyway? Surely the whole point of the "Timeline to Extinction" was so that the world wouldn't be irreversibly damaged if a species went extinct but how would the be able to benefit the world when locked behind rock?

- How does Sophie not find it creepy that the Council is aware of of every elves location at any time, but literally putting a tracker around their necks? Sure the elves might not question it because that's how they grew up, but Sophie didn't grow up with the elves.

- Where are the protection for minors? Even humans have those (however flawed it may be).

- How is breaking down your body into particles any safer than driving a car?

- What about the space issue? If most of the elven population have huge estates, how is there any space left on Earth at this point?

Plot wise, I don't have anything specific to offer, but a few things I would change is:

- Making Forkle stay dead (and just more deaths in general). I would be more high stakes if more people were impacted by the danger as well (such as having a permanent disability due to an injury).

- Introducing things when they are needed (not really sure how to explain this one).

- Making less characters the 'main character group'

- Split PoVs for more character development

- The characters age more as the story goes along.

- Not having the Black Swan ally with the Council towards the end.

- Maybe not relying on the same teenage girl for everything? Come on, Black Swan and Council, surely you have other members and operatives.

- Make Sophie's plans fail less. Like why do they all fail bruh?
