Anathem has easily his most complete ending, where there's even something of an epilogue after the plot threads are wrapped up, but sadly a lot of the stuff after it was a bit of a regression either in quality of ideas or of ending or both. (Anathem hides the central plot elements of the book until at least halfway through, though, which could be offputting on its own if you don't click with the world-building before that. But personally I greatly prefer that to the pedestrianness of a Reamde or Fall or even the front end of Seveneves.)
