Not for me. Heavily military/war focused which is not my thing anyway but I am capable of getting invested in any plot if I'm invested in the characters. Unfortunately all the characters in this book (and their relationships to one another) were severely under-developed and uninteresting. This includes Rin. Amorality is not the same thing as a complex, compelling character psychology (the prose is also at fault here as it is lacking in subtlety and leaves no room for subtext). I found her motivations to be extremely weak and she just never jumped off the page for me.

All this might make it sound like a terrible book, but it's not. If you, like me, prioritise deep, real-feeling characters and beautiful prose, then yeah, you probably won't be impressed with it. However, if you love fantasy for the magic, the world-building, the bloody battles and epic scope - and don't mind if the characters are merely serviceable to move the plot forward - I'm sure you would thoroughly enjoy this. It is genuinely very good at being an action-packed,  mystical spectacle. Hell, many people do in fact recommend this series based on Rin's supposed complexity which is why I read it in the first place, so it's not even guaranteed you'll find the characters as flat as I did.
