Shades of Grey 2

I really loved the first book (shades of grey). It took me quite some time to get into the second, as it felt more like a continuous try to fit a lot of explanation into all that was happening. And I did not like the internal jokes, the protagonist was telling on how he was clever ones, just to retell something.

I really liked the second half of the book, as it felt more like the original first book. But somehow, the ending left me a bit frustrated with all back and forth until ultimate things happened. Still for me, quite a nice twist of what I was expecting and how it turned out. So rather four stars than three.
