In a moving tribute to brotherly love, impossible decisions, the promise of youth and the tragedy of growing up too soon, The Unmoving Sky is a page turner of survival and adventure. The main characters, Jackson and Artie, came alive on the page and the details of their shared pain was heart-wrenching. The detail of this novella speaks to the talent of the author. In every scene I could smell, see, feel the environment described; it was visceral at times and completely sucked me in. My one complaint is that I feel the story wrapped up a bit too quickly. I think there was more that could be said of the dangerous hermit that lived in the woods and his relationship with Artie. A strong four stars and I will be looking for more from K.L. Hallam.
