I've read somewhere that
Iain Banks has decided to write a book every two years (alternating SF with mainstream) so it might be a while till the next SF from him. Pity.
It also seems a pity that
Alastair Reynolds will no longer write stories in his
Revelation Space universe as I enjoy those stories. FYI, he has written short stories based in the same universe some of which are in
Gardner Dozois' (editor)
Best Science Fiction of the Year Anthologies. A plug here for Dozois' books as they are usually hefty and contain much in the way of excellent short stories, space opera and otherwise. Short stories is where writers tend to take more risks, with stunning results. A must have if you have any interest in the current state of the genre.
As for the
Peter F. Hamilton books, I really liked the
Night's Dawn except for the ending which was too deus ex machina for my tastes; the same problem I have with
Fallen Dragon. I preferred his Greg Mandel books beginning with
Mindstar Rising.
As for other Space Opera, though the following may/not be Space Opera depending on your definition, read and liked:
David Weber's Honor Harrington series
- a Hornblower in space featuring a woman as the hero(ine)
- military SF
- begins with
'On Basilisk Station'.
Lois McMaster Bujold's Miles Vorkosigan series
- begins with
'Warrior's Apprentice' although there are novels from earlier in the timeline that feature his parents.
- not sure if it's really Space opera but highly recommended.
A warning about
John C. Wright's 'The Golden Age' and
Tony Daniel's 'Metaplanetary' both of which are excellent and are space opera, both are part one of a two-parter. So if you start reading them now, you may have to wait for the conclusion.
You can get a taste for Tony Daniel's writing
