I gave up on this after reading about a fifth of it.
First of all, the writing needs some work; it feels clunky, and the constant foreign words and translations distract from the flow of the story, rather than adding to it.
Secondly, it feels like there's very little emotion in any of the characters. They don't react to events in relatable ways, so I just couldn't bring myself to care about them. Cheating wife? Oh well. Massive life changing revelation? Oh, the protagonist says, my father can now find me "someone more worthy of me" to marry. Ugh.
However, what really made me give up was the two teenage girl protagonists. They talk and think about boys and marriage, and not much else. (To be fair, they also occasionally think about escaping their current life... and the new boys they'll meet.) When their mother reveals some life-changing news to them, their thoughts are about how this changes the kind of boys they can get.
Ugh. No. There's more to life. I give up.
