Abaddon's Gate

This was, I thought, a great end to the series.

And it SHOULD have been: they should have done a Hamilton, and unlocked a whole new series, based on the Gate - but they didn't. Opportunity lost. Because this was really good, although I was starting to get a little sick of our unkillable, yet fragile, just-too-noble hero.

Oh, the subplots weave in and out, and the physics is warped, and the private eye in the hat is infuriatingly cryptic - and the action keeps up, and the characterisation is (generally) good, and it is one of my new favourites.
