Seeking Ferret

I recently read this as well. I found it jarring how much of the language to describe the arklets and the orbital mechanics he borrowed from his Anathem, but I might not have noticed it if that book weren't my most re-read audiobook. I found Seveneves to be a grim commentary on how horrible humanity is, that even as the species is facing extinction we still get people literally and figuratively backstabbing each other for individual gain. Even 5,000 years after we should have learned better from this experience, we still have two factions within the spacers at war with each other, and when they find Earth is already populated with two other human subspecies what do they do but divide them into their two factions as well?

I was also really irritated with Stephenson's choice to have Probst's ship leaking nuclear fuel into the habitat areas, and then contaminating the remaining Izzy and Arklets. Nuclear power is not the same as thrust, you can't give a ship more thrust by building more nuclear reactors. There is no reason for nuclear power closer to the Sun than the asteroid belt, they could've gotten by on just solar panels, so I didn't see an explanation within the book for why it had this big powerful nuclear time bomb. The Wikipedia page says the nuclear power was to melt the comet for thrust, but if so, that wasn't sufficiently explained in the book for me.

And not to mention, it drove me nuts that the book never explained the Agent that destroyed the Moon.
