I was slightly upset to discover that the rest of the novels in this universe are not centred on the Goblin Emperor Maia.  Instead they are focused on Cellehar , who is a minor prelate that can read the Dead's last thoughts and determine some circumstances of their death 

He played a pivotal role in The Goblin Emporer and we learn of his traumatic backstory that had him leave his religious brotherhood and work as an independent.  

Now we see Cellehar in his new role dealing with lost wills and helping petitioners sort out their relatives and question about their dead. 

There is a murder he has been petitioned to solve and within that story, we see Cellehar make his way as a Speaker for the dead, uncovering smaller mysteries,  being a political pawn in another's play for power,  dealing with the grief of others all the while confronted by his own past, his loneliness and guilt.  

Addison has such a way with the inner emotional life of her characters as they navigate their ways in a strict and formal society.
