Oh and I forgot this one...

Vorkosigan Adventures by Lois McMaster Bujold

Miles Naismith Vorkosigan is not your typical sci-fi hero, he's not handsome or particularly tall but he can swindle you out of your teeth if you aren't careful! Born short and with bones that break at the slightest pressure, he never had much of a chance in mutant-hating Barrayar so he made an alternate identity elsewhere and conned the Barrayar Imperium into paying for it (paraphrasing the author's words). Admiral Naismith of the Dendarii Mercenaries goes around doing the dirty work for Imperial Security and having a grand old time now and again. Miles saves the day but not without cost, sometimes high.

Miles is way better than James T. Kirk of Star Trek. He's not perfect and slightly insane like most normal people. A quote from my favorite book in the series:
