Silman's Complete Endgame Course has got a lot of good reviews from both my local club players and Amazon reviews.
Is there any chess book exclusively for endgame study?

BTW you probably can't go wrong taking IM pfren's advice
I suggest, 100 Endgames You Must Know by De la Villa

I'd rather go for the Keres and Shereshevsky classics instead (Practical Chess Endings and Endgame Strategy, respectively).
But anyway, Silman's book is probably the best he has ever written, you cannot go very wrong with it.
It is his best.
I found the Seirawan Winning Chess series to be very good. I don't actually own the endgame book but I have several others and they're good (some more than others).

I basically sucked at endgames and they bored me, but Silman's book helped me not suck as much and taught me that endgames are anything but boring. It's nicely set up to teach you only what you need to know depending on your chess rating.

There are quite a few such as Devoretsky's Endgame Manual and Silman's Endgame book. I would advise you take a look at these comprehensive chess lists that cover a lot of endgame books. You can just choose one that suits you or you find will suit you best. There is this site http://www.squidoo.com/chess-reference, and this site http://home.comcast.net/~danheisman/Events_Books/General_Book_Guide.htm. There is also a small article about pawn endgames here http://www.squidoo.com/chess-endgame.
I am looking forward to study end games in great detail. Is there any book which discusses this in great detail? Thanks in advance...
Cheers,
