I like it a lot less than I thought I was going to. And the thing is, I don't know WHY!!! It's doing so many different things that I generally find extremely compelling, and yet when all put together, I am left feeling cold.
Yeah, I felt similarly about Vasya and it was frustrating. Especially on second thought I remember not finding the ending very satisfying. But I read it three years ago so I forgot the details.

(Btw, I wrote a missing scene with Sasha and Dmitrii: The Cost of the Second Lie /self-promo)
