Re: Re. Forget the film..
Palimpsest by Charlie Stross
Haven't read it, but since Stross started his career with hard-SF novels that try to deal rigorously with causality problems, I'd expect he does a pretty good job. I'm hard-pressed to think of another author I've read who puts so much effort into logically-consistent treatment of a topic that's inherently about inconsistency. Singularity Sky turned out to be not quite my cup of tea (the cat-and-mouse spy-game stuff rubs me the wrong way), but I really appreciate how Stross grappled with those issues.
He's also the only hard-SF author I can think of offhand who writes space combat with any verisimilitude.
