See book 3 in the series.

Since I haven't read The House of Shattered Wings, I'm missing a lot of the context for this story, so it took me a bit to get into it. But it does come together as a story, with an exciting glimpse of several magic systems and a bunch of haunting memories. Still, it's very much an "interquel", with little time spent getting us up to speed and not much finality to its ending. ( )
