Kaeya's eye Heh

It took me whole 10 days to finish this book this is cause... At first half of the book I was quite bored and the story didn't seem to progress ...so I left it... But then one day I got the motivation to read to again and complete the whole book...I am quite glad I did ...it was the very last sentence of the whole book which was the plot twist....and...believe me it's really good, finished the other half in just one day cuz I was so excited to know the ending...plus the narrating style was good as it was giving everyone's perspective In short it was mind blowing, it was as they said "will have u madly turning the pages".
