What book should I refer to to begin learning chess? I'm a highschool student and want to play chess seriously. A friend of mine taught me the basic rules of the game. What book should I refer to to begin learning chess? 

I tried Capablanca's Chess Fundamentals but got stuck in the first chapter due to notations, I did not quite understand what 1K-K7 and things like those meant.

I'd love if you could give me an ordered list of books I can read :)
Learn Chess by John Nunn. A highly respected chess author. Do not be put off by the title!

Silman's Complete Endgame Course by Jeremy Silman. A modern classic, improvement in the endgame will improve your whole game, I should recommend studying up to the Part Five then saving the rest for later.

Tactics Time! by Tim Brennan and Anthea Carson. Tactics is an essential part of chess improvement.

How to Reassess Your Chess by Jeremy Silman. A challenging book but a good study of it will leave a permanent mark on you. 

I believe that intense study of these four books will yield very good results for you. I recommend studying them in the order 


Learn Chess
Tactics Time!
Silman's Endgame Course
How to Reassess Your Chess 


The most important thing to do is to keep playing, once you have studied these books and feel that your level of play is better, check out Dan Heisman's Book Recommendations for further reference

Edit: Post RemcoGerlich's comment I have decided to change Build up Your Chess 1: The Fundamentals to How to Reassess your Chess as I realized that the Yusupov book is actually quite challenging and less approachable than Silman's. Although it should still be recommended for when your level of play is higher.
