There are not many books like "Living For Pleasure" which I personally would recommend. Haris Dimitriadis' "Epicurus and the Pleasant LIfe" probably would be next on a list geared to your specifications. You might also like Catherine Wilson's How To Be An Epicurean.
The recommended reading list in our FAQ is geared toward helping people read the works of the ancient Epicureans directly, as that is a far more accurate way to find out what Epicurus really taught:
Less in line with your specifiication to be short would be:
1 - Norman DeWitt's Epicurus and His Philosophy, which is the best "textbook" treatment of Epicurean Philosophy
2 - A Few Days in Athens - which conveys Epicurean philosophy in Fiction form but is probably the most true-to-form original work on Epicurus written since the ancient world. You can read that online here: AFewDaysInAthens.com
