Incredible (PLEASE READ!!!)
The only word that is close enough to even slightly describe the contents of this novel. I pretty much made an account just to be able to communicate with you, the author.
I'm still trying to figure out what is going on with Claire... You gave some clues in another comment, but unfortunately Google translate failed me once again... Could you perhaps help me out? So far I think that Claire was imaginary, her purpose only being a way of explaining where the e-mails came from. Was she Ciarán's DECEPTION? Did he try to deceive himself by personifying a part of him; acting like it was her/this part's fault for sending the messages? Maybe she is the part of Ciarán that wants to stay away from people. So when she wanted an answer on Graduation day it was litteraly Ciarán asking himself wether he wanted to stay alone(be with Claire). In the end we saw him propose to her. Perhaps he decided to stay alone(with Claire) forever? What I still don't get is how other people still see her as a person... Maybe it's Ciarán speaking or what he is currently thinking... Although it wouldn't make sense since when they were playing poker Claire won and Luce congratulated her (kind of). Then again when they were competing against each other Luce told Ciarán that he had won once previously and she had won once too. So was Claire's victory a lie? Had Luce won on the poker match or was victory hers too since Claire was on the girls' team? Also, Claire's sudden appearances and the fact that Ciarán said she was always with him kind of give us a hint about her non existence. I need to read this again but these are my current thoughts. Though, in conclusion I think she's the other part of Ciarán. The one afraid to be with people. Let's not forget that when Ciarán left the phone on the desk to talk to Claire no one really spoke, since Luce didn't hear a thing. I feel like Ciaran was lying to us; the readers (or maybe even to himself).
END OF INCREDIBLY LONG SPOILERS~~~~~~
Now, the other thing that caught my attention were all the greek related names. As a greek myself, I found it fun to realise that some of the names you used have greek origins, or they even are greek words written with English characters. For example Luce Aurea. Here you obviously used the greek adjective ωραία (meaning: pretty, good looking). You explained that Endyein comes from greek too. Also Claire's surname is a greek name nowadays (Argyris / Αργύρηs). I'm confident that in Ancient Greece you could've found someone with that kind of surname since most people used their father's name as a surname. For example: if we used this kind of surname method nowadays if your father was named, for example William your surname would be Williams. Surnames like these still exist but we are no longer named after our fathers as you probably know already. Sorry I started ranting... I got a bit excited that's all.
Well...This is more like a letter to you now XD
If you read this far, thank you! I've never really written a comment this long... But I'm not exactly a fan of comments either, since I'm either too bored to write anything or too shy to state my opinion. But your story made me want to desperately try to get a few answers and opinions out of you. I really hope you reply because I'd love to hear your opinion on my theories.
