I would recommend The Art of Wargaming by Peter Perla, as it stands the test of time and is a myth buster and gives good practical common sense explanations. No magic, dispelling the aura of professional omnipotence and getting to the "heart of the game" for the "benefit of the players". It is all about the communication and narrative of the event.

This is worth reading (or listening to in the final minute of the video) as advice to anyone interested in recreational and/or professional wargaming (see below, I can testify that Peter Perla had time for anybody, he even game me ten minutes):
The annotated page of advice that Peter Perla wrote to Colin Marston inside the front cover of Peter's Art of Wargaming book (magnus opus) that rings so true! No finer words sum up wargaming! (If you cannot read the handwriting then it is worth listening to in the last minute of the video).
