House of Suns, Alastair Reynolds

Some quotes from what I think is my favourite book:

Our family’s symbol was a black cinquefoil; his was a pair of intermeshing cogs, the emblem painted on the ship’s sleek, flanged hull.

You are a bookworm who has tunnelled through the pages of history. Is that not so?’

If my years as a shatterling had taught me anything, it was that not all questions had answers. Societies had reduced themselves to radioactive dust because they could not accept that single unpalatable truth.

That it was a Homunculus weapon was beyond argument: I was seeing it from a foreshortened perspective, but Dalliance was able to extrapolate its true form, and the delicate, slender-stalked flower-like shape, its maw a coronet of diaphanous petals, veined like dragonfly wings, was an uncanny match against data in the trove.

He just became something weirder, larger, faster than he had been before. The old mansion was now a shining, rationally organised edifice.
