"...for the most part, you give a man something to look up to, you tell him that he can be something more than he is now, more than other people think he'll ever be, and he'll try his goddamned best to make it true".

Jade is a valuable commodity amongst the Janloon. The two main tribes (No peak and Mountain) claim territory across the city and live side by side uneasily. 
Within each clan there is a strict hierarchy: from fingers, fists to horns and the pillar (lowest to highest) and the weatherman, luckbringers...all are green bone practitioners who uses Jade to enhance their powers. Jade is also won by challenge or stolen. Each clan has a strict hierarchy and violations of this lead to immediate retribution. 

The Kauls are the leaders of the No Peak Clan and hear of a new drug which allows non green bones to wield Jade, without training. This story revolves around the Kauls, where the new generation are taking the Horns (so to speak) and pushing past the previous generations tolerance and wariness around respect, history between the clans and moving towards a new era where they are battling a new drug which threatens their way of life...but the rival gang The Mountains seem to be moving onto the No Peak territory. 

I have seen many rave reviews for Fonda Lee and made an effort to finally pick this up; this did not disappoint. I was sucked into the narrative, world building, honour code and world of the Kenon. I really enjoyed the strategy, politics and the colonial history weaved into the story. This is a perfect blend of East and Western influenced fantasy. This is the first book of the trilogy which I will be diving into.
