Some of the few true space opera novels that I've read have been the novels in the series based on the Halo videogames. I'm currently reading the fourth book, Ghosts of Onyx by Eric Nylund (the books are written by different authors, but Nylund wrote several). As you might expect from books based on video games, these novels are heavy on action and light on philosophical or literary ramblings. This doesn't necessarily make them bad, but in my opinion the quality varies from book to book.
I like the setting of these novels very much. The presentation of a future, space-faring humanity is more believable than the sci-fi stereotype. Human soldiers don't use laser-shooting plastic squirt guns! ;D Also, the hostile aliens are actually alien; they're not just people with lumpy heads. Finally, there's an intriguing mythology behind the scenes having to do with a mysterious, extinct race of beings who inhabited the galaxy long ago, leaving behind strange technological relics to which the aliens assign religious meaning.
