Good endgame book

I recently bought "Silman's Complete Endgame Course". Did not had the chance to work with it a lot but it looks promising (quite complete).

I love Dvoretsky's Chess Endgame Manual. Its great both for beginners and for experienced players, with some really tough exercises and great theoretical explanation.

Mikhail Shereshevsky - Endgame Strategy

For your level, Silman's endgame course is quite good - especially because it's organized by level of play. Instead of going topic by topic, it goes difficulty by difficulty. So you get the best bang for your buck, no matter what level you are.

Do NOT get Dvoretsky's Endgame Manual. It's extremely dense and slow to read. I'd definitely recommend it to expert+ players because of how thorough it is. I feel like it's only for players who already have an extremely good grasp on strategy and board visualization.

I recommend "100 Endgames You Must Know" by Jesus de la Villa. It's incredibly helpful and will not overwhelm you like Dvoretsky's book. Silman's is good, but it's not designed to study and continue - his book I'd recommend as a supplement, as it's meant to ladder up with you ELO as you get better.

I do not have any immediate interest in studying the endgame. My current level of play seems to dictate that I focus on the fundamentals. Tactics and positional ideas I dabble in from time to time, though, the fundamentals of chess is always my main focus. It seems to me that studying endgame books is something more suited for 2000 plus rated individuals... Am I misguided with this notion of the endgame? Curiously, are there any books that deal with the endgame strictly from the vantage point of the middlegame? Preparing for the endgame in the late stages of a middlegame that is destined for endgame? I may be interested in such an endgame book. Calculation; Law of opposition; Triangulation; The Philador; 'Endgames you must know'; 'Famous endgame studies'; etc. It all seems like so much mental clutter that has nothing to do with the game of chess... A GRANDMASTER could beat me in less than 25 moves a 100 times in a row just by knowledge of the fundamentals, tactics, and positional knowledge... That's the way I see it.

@Celestial_Object, by learning the endgame first, you can start to engineer middlegames that lead to endgames that favor you. It's like having a cheat sheet on a test.

You're right that without work in other areas (tactics, etc.) you will reach the endgame fairly infrequently, but by understanding endgame motifs, you can develop your middlegame plans and strategy in a way that benefits you.
