- The Revenant by Michael Punke
This was brilliant!
And I say that as someone who has zero interest in Wild West tales, Indians, etc. As Leonardo di Caprio's film made known to many, The Revenant is the story of a fur trader that gets attacked and horribly mauled by a huge bear, who then gets abandoned by his colleagues and fights to survive harsh elements, hunger, and hostile Indians, with a burning desire to get his revenge.
There are a number of things I found exceptional in The Revenant. One of them is the very detailed way in which the day-to-day survival of everyone in the book is explained. Just like finding the next meal is a major part of their day, it becomes a major part of the book. The reader is absorbed into the actual daily worries and (gruesome, gruelling) work that goes into surviving in the wild.
I also loved how the narrator goes from one character to another, sometimes in the course of a dialogue, and tells their life stories, often starting from childhood. I was again surprised to find out at the end that this is a true story and that most of these characters, including Hugh Glass and his two betrayers, were real people on whom quite a few books were written 
Aside from the amazing and very worthy story it tells, this is a book that can (and should imho) be studied at Literature classes. There are layers of meaning and it has important things to say about character, loyalty, life in general. Some of these are imparted to the reader while talking about hunted animals. The parallels with the characters are stark and unavoidable.
The narration is cool and matter-of-fact, refraining from tugging on heartstrings despite the extraordinary hardships and pain on every page. As regulars of these threads well know, I like that. A lot.
I heartily recommend this book to everyone here. I find it similar to This Thing Of Darkness in many ways - tone of narration, well-researched historical novel that is almost non-fiction, etc.
