Capablanca's Chess Fundamentals is excellent for this. Or if you want a book that specialises in endgames, I believe Yuri Averbakhs' book is the classic.
I know Danko_25 already mentioned it, but the most helpful book I have ever seen on endgames is Mark Dvoretsky's "Endgame" manual. The nice thing is it's a handbook so you don't have to read it cover to cover. Lookup the section on king/pawn endgames and study.
