@mattly I don't even know how I feel about this book and its degree of believability. Like, it makes 2 little conceits. 1 is that the scenario is possible at all. And 2 is that it's survivable at all.
And I can grant those. But I needed it to go all the way. It has to make that worth it. And seveneves stops just short of all of the most interesting bits.
It should have been two books. That or the first half should have been a prologue and we just completely handwave the physics
