This was a re-read, the first time I read it was back in 2015, when I was a novice in terms of fantasy lit. I can't add anything that the hundreds of reviewers before me haven't left but I am sure that there are only a very few who can near Erikson in terms of world-building, managing expansive cast and the action drama.
This is the book where everything starts to make sense, where the bigger players are seen for who they are. This is a book where heavy concepts like mass hypnosis(present day media?) and the twisting of truth that lead people commit heinous things, are dealt side by side. The Bonehunters actually is two books in one.
It was overwhelming back then, it is overwhelming now.
Loved it back then, love it more now.

P.s I've heard so many complaints about how the weird or even complete lack of a sentence structure in many places turn folks off from reading Erikson, but it is prose. It is meant to convey more than just information with words. He uses it perfectly, be it in fantastic action sequences near the end with Kalam or the heart wrenching stuff in Icarium's story/Y'ghatan. Erikson blasts the rules and structure out of the window and makes the words convey a fantastic tale, and I love his work more for that reason.
