Ninth Life a standalone sci-fi novel in The Factus Series. I had not read this author's books before, and I wasn't sure how I would enjoy them due to my limited experience reading sci-fi novels. However, I found it to be extremely engaging, and the writing style (epistolary-esque) was easy to absorb. The writing was very atmospheric, and I could practically feel the heat radiating from the desert sand.

I particularly enjoyed the segments where the author used the second person perspective. I don't see this used often enough, and it felt like it really put me into the story and the bodies of the characters.

The world building was exquisite, and I loved how Holborn played with every aspect of the universe that they created. The rules were constantly changing and kept the reader on their toes. I felt as though I couldn't read this book fast enough, and that hasn't happened to me in quite some time. I look forward to reading the other books in the series and staying in this world for as long as I can!
