It's probably the best fantasy book ever written.

It's stunning in so many ways. It really reads like someone who has never seen any of the generic sub-LotR shit that passes for most fantasy and just started to write something from first principles of fantasy, namely literally anything is possible.

But is also a fantastically political and pointed and the whole book is about the scars and horrors of colonialism.
And the prose is beautiful.

Truly original, well written/plotted and has a purpose. Any one of those is a rare thing indeed in fantasy. All three is almost unheard of.
