Re: Your Top Ten Science Fiction Writers, and then some.
Now if you like the Traveller RPG, run, do not walk, and find a used copy of The Shattered Stars by Richard S. McEnroe (1985, http://www.bookfinder.com is your friend).
Gives incredible detail about the trials and tribulations of a free trader, along with a story including a grizzled captain, a skittish engineer lady who is a secret telepath on the run from an evil Psionics institute, a war-weary super-soldier who just wants to forget, a super-bomb that various factions are trying to get their hands on, and a rogue mega-telepath super villain.
A pity that none of McEnroe other few novels were anywhere near as exciting.
