At the risk of being that guy who is always last to stop using a meme, but here is the next best light and fun book (after princess bride). I highly recommend The Warrior's Apprentice by Lois McMaster Bujold. Its SF, but it has the best character development I have ever read. Miles Vorkosigan is an awesome character with flaws, brilliance, insecurities, bravado, confidence, and ostracizing impairment, a powerful family. etc. All of the various character traits are well developed and all together make a reckless Hero you can't help but love
Here is the first 5 chapters.
