I spoil a bit but carefully.
I don't like the main character. The story is about how she changes and become somewhat better than the ones who tormented her but, well no. She doesn't. Cain did not deserve his fate. everyone is punished and tricked and this is completely unreal how they're tricked anyway.
this story only tell us the winner doesn't have to be the good guy but the smart and manipulative one. This is morally really upseting. Then, if for example Isis came back, learned from her mistakes and rewrote its history she would change it again as aria did ? This is really kind of lame and poor. And why did they need to have the main characters meet as children? It's cliché and pointless. And of course they don't know. And i don't even bother to mention Chloe. Arf, i'm reaaaally desapointed.
