I started with Fleet Action (thanks to the CIC! yay), and it was the one that really got me into reading the rest of 'em. Then I had a wierd order of just whatever I could find and when. First was FA, then I read Freedom Flight, then Price of Freedom, Action Stations, Pilgrim Stars, and i've yet to get a copy of the movie novel, False Colors, End Run, and Heart of the Tiger.
Fleet Action was defiantly the best i've read, and Freedom Flight had some cool parts to it. Price of Freedom was ok, Action Stations was alright, and Pilgrim Stars was decent.
