Paul Keres's Practical Chess Endings is accessible, and has a lot of useful tips and ideas. It's probably my favourite endgame book. Also you might want to take a peek at this thread on a similar theme:

Now I want to ask the Chess.com comunity to help me decide on a new endgame book. Do you have any suggestions? Please I know this is kind of random but this could mean win or lose for me. Remember I'm not good with endgames.
