Those Beyond the Wall by Micaiah Johnson
Mr Scales, a top Ashtown enforcer, is doing just fine until a gruesome and impossible murder occurs right in front of her.
I liked this book a lot, but an element detracted just enough to stop it being a 4-star rating for me. Because spoilers I shan’t mention what, suffice to say it features a certain theme found in speculative fiction that I’m not fond of. That I still enjoyed the book as much as I did is a testament to Johnson’s skill. The writing is good and engaging, the story interesting and the characters complex and multi-faceted. ★★★☆☆
