First couple of chapters was interesting - unusual. I love unusual! But... *ack* I dunno... after that initial hype... it was just... meh. Which soon turned into: for fuck sake, is it over yet?!?!
I’m struggling to pinpoint exactly what it was that bothered me so much about the book: the characters, the dialogue, the writing, all of it...
So, here are a few words that come to mind, because, to try and explain the depths of what I feel about this book halts me. And I cannot for the life of me bring full sentences to my mind or fingertips:

Boring
Tell not show (irritates the shit out of me in any book tbh)
Pointless POINTLESS dialogue
Lacking
Drivel (so! much! of it!)
Despondent
Non-absorbing
Tried too hard to be funny
Ridiculous
Sir Arthur Conan Doyle wannabe (sorry not sorry)

In the book a character mentioned how the Germans have a word for various feelings and acts and tendencies etc. And I wish there was a word that described how I felt about this book.

Do not recommend. soz

The only positive thing I can take away from this book are all the new words I’ve learnt, and that’s probably why I generously gave it two stars.
