Best introductory endgame book?

Recently I went through this one in detail, which was pretty decent...

Pandolfini, Bruce. 1988. Pandolfini's Endgame Course. New York, New York: Fireside.  I like this even more.  

...but it's probably not the best. Although it's a very nice overview that mentions a lot of interesting exceptions, I felt it was poorly organized.

ENDGAME 26

W: Kb4, Qd2 B: Kb1, Qa1

White moves and wins

Forced Mate

8/8/8/8/1K6/8/3Q4/qk6 w - - 0 1

From the sublime to the ridiculous. Your opponent Queens a

pawn before you do. Imagine the relief when you manage to

equalize the game and Queen one yourself. As a draw appears

certain, your opponent moves up his King and threatens mate.

You are shocked when you realize that your pieces, stumbling

over each other, cannot organize a defense. Such could be the

case when your pawn-made Queen occupies a Rook's file.

After White's King Intrudes [sic] at b3, Black succumbs to the multi-

ple threats of Qc2, Qd1, or Qe1.

1. Kb3 Qc3+

2. Kxc3 Ka1

3. Qb2 mate
