What I Read: Book Releases June 2021
The Witness for the Dead (The Goblin Emperor #2) by Katherine Addison

Genre: Adult Urban Fantasy Mystery
Pubdate: 22nd of June
Publisher: Tor Books
So, while it says it’s #2, it’s actually a standalone novel. But it is set in the same world as The Goblin Emperor. So, Maia, the young half-goblin emperor, wanted to know who had killed his father and half-brothers, and then he turned to a Witness for the Dead named Thara Celehar.
Thara Celehar lives far from courts, in somewhat of a quasi-exile, serving the common people of the city. His duty is communicating with the dead. Still, Celehar will follow the truth wherever it leads him and no matter who may be implicated in murder, fraud, or ancient injustices.
I finished this book in only two days. Just to paint the picture more clearly: on average, a book like this would take me a week or so.
Make of that what you will.
I have to admit; I did have to get into it at first. The language use, difficult terminologies, and overly formal dialogue threw me off. However, once I got into it (and luckily, the dialogue wasn’t always that formal), I was hooked and found it very difficult to put the book away. Hence the two days.
It felt extremely satisfying to watch those plots weave themselves together, all the way to the final climactic moment, and we find out what actually happened. The ending in itself was satisfying but bittersweet.
Celahar was also a very likable character. He wants to do the right thing and make sure the dead have their justice. At the same time, he’s very self-conscious, always expecting people to think the worst of him and being afraid. It broke my heart a little bit each time he felt surprised that someone would actually treat him with kindness and gratitude.
If you enjoy a good murder mystery set in a fascinating magical world, with likable and memorable characters (although all have difficult names), you won’t be disappointed with this one.
