I would recommend this book, but I think you'll know if you can reach the good parts by the first few pages/chapters. The writing style is indeed very unique - it's mostly told through a pattern of interviews and memories. That said, it's a pretty slow start. At first, I thought the interviews were just a gimmick and that it would make me bounce off from the book as a whole. But the way they were written and the characters themselves kept me just invested enough to continue. Each interview left me wanting to know more about each character, and it delivered by presenting me withone of their memories. So I simply never had the chance to bounce off of it like I thought I would. And boy am I glad, because after a certain point, you start forming your own hypothesis about what happened, and by then, you're already firmly invested.

The story is far from generic or predictable. I would be surprised if someone could guess the outcome of the hero or the surrounding events. But it's not just random either. Nothing is hand-waved away into "it just works". Everything has a proper explanation for happening or for why something was explained a certain way. The author had a plan for everything he included.

This is a mystery book first, fantasy second, and the drama comes once all of the pieces of the mystery get presented.
I went into this book blind, and was not disappointed.
