Calamity recap

Prof has fallen and taken a city, and the surviving Reckoners are fugitives. David's position is now the team's working theory: Epics are driven to cruelty by fear rather than by power, and facing that fear can undo it, with Megan as the proof. They track Prof to Ildithia, the remains of Atlanta, a city built of salt that crumbles at one edge and regrows at the other so the whole thing migrates across the country. Operating under cover, short of equipment and dependent on the maker Knighthawk, they try to reach a man who invented every method they use against him, while the power-stealing Epic Larcener attaches himself to them and the city-destroying Obliteration pursues his own plan. David's investigation into the origin of Epic powers points at Calamity itself, and he finds a way to reach it. Calamity proves to be a being that came here and gave out powers, and Larcener is another of the same kind. David forces Calamity to withdraw, Prof is freed and restored, and David ends the book an Epic himself.

Previously: a red star called Calamity appeared and ordinary people began gaining superhuman powers, almost all of them using those powers to rule or destroy. David Charleston joined the Reckoners, the only organisation that assassinates Epics, and helped kill Steelheart, who had turned Chicago to steel and ruled it for a decade. He learned that the Reckoners' leader, Prof, is himself an Epic whose forcefield, healing and matter-transmuting powers were lent to the team through equipment, and that his teammate Megan is an Epic who returns from death and can briefly pull people and objects out of other versions of reality. In Babilar, the flooded ruin of Manhattan, the dying High Epic Regalia manoeuvred Prof into using his powers under extreme emotional pressure so that he would fall to the corruption they carry, and he did. Megan, meanwhile, learned to use her abilities without being corrupted, by facing her fears instead of avoiding them. Prof broke with the Reckoners and left, and David resolved to reclaim him rather than kill him.

Prof, fallen and fully corrupted, has taken control of a city, and the Reckoners who are left, David, Megan, Tia, Cody, Abraham and Mizzy, are fugitives without a base or a supply line. David's argument has become the team's operating theory: that Epics are driven to cruelty by fear rather than by the power itself, and that confronting that fear can reverse it, with Megan as the standing proof. Their objective is therefore not to kill Prof but to reclaim him, which most of the surviving organisation regards as sentimental and likely to get people killed. Tracking him leads the team to Ildithia, the remains of Atlanta, a city continuously rebuilt out of salt: it crumbles at one edge and regrows at the other, so the whole city slowly migrates across the landscape.

The team establishes itself in Ildithia under cover, learning a city where the buildings dissolve on a schedule and everything has to be rebuilt weekly. It is nominally ruled by Larcener, a High Epic who absorbs the abilities of any Epic near him and who cannot be bothered to govern anything. The Reckoners are badly short of equipment, and the only source is Knighthawk, the maker who has always supplied them: a man who is almost entirely paralysed, uninterested in helping them, and whose devices are built from components taken out of dead Epics. David also has to face the team's real objection to his plan, which is that trying to save Prof rather than kill him is a risk the survivors will pay for.

Prof arrives in Ildithia and takes it, displacing Larcener, who attaches himself to the Reckoners instead and proves to be as unhelpful in their base as he was in his palace. The team is now operating inside a city held by the man they intend to rescue, against an opponent who knows every Reckoner tactic, item of equipment and habit because he devised them. David works on how to force an Epic to confront the fear their power feeds on, using Megan's experience as the template, and looks for a way to weaken Prof enough to get near him. Obliteration, who survived Babilar, is also in the city, pursuing a purpose of his own.

The Reckoners' operations against Prof are expensive. He anticipates them, and the team's losses are severe enough that the argument over whether he can be redeemed turns bitter. David pushes further into the question he has been circling since Babilar, which is where Epic powers actually come from, and the answer keeps pointing back at Calamity itself, the red star that appeared on the night the first Epics manifested. Knighthawk's technology, which is built out of Epic remains and grants borrowed abilities to ordinary people, turns out to say more about the nature of those powers than anything the Reckoners have studied.

Prof's grip on Ildithia tightens and the Reckoners are forced further into the open, while Obliteration's own plan for the city runs alongside everything else. Working from what Knighthawk's devices imply about Epic bodies and from what Megan can do with other versions of reality, David concludes that Calamity is not a phenomenon but a source, and that it can be reached and confronted directly. The team, short of people and of options, commits to a plan built on that conclusion instead of on any conventional assassination.

The confrontation with Prof comes to a head in Ildithia, with David committing to the only version of the plan that could work: not killing him, but forcing him into a position where he must face the fear his power is built on, the same way Megan faced hers. At the same time David goes through with reaching Calamity itself, on the reasoning that whatever gave out these powers can also take them back, and that everything about the last decade follows from what Calamity actually is.

David reaches Calamity and finds a being rather than a star: an entity from outside this world that came here and gave people powers, and whose gift carries the compulsion toward cruelty that ruined nearly everyone who took it. Larcener proves to be one of the same kind, an earlier arrival hiding among humans. David confronts Calamity, refuses what it offers him, and forces it to leave, ending its hold on the world. Prof is recovered rather than killed: freed of what was driving him, he is himself again and returns to the Reckoners, though marked by what he did. David is changed too, ending the book with abilities of his own, which makes him the sort of creature he spent his life hunting and the first real test of his own argument that an Epic can choose otherwise. The Reckoners are left in a world that still has Epics but no longer has the thing that made them monstrous, with rebuilding rather than resistance ahead of them.

David reaches Calamity itself and finds that it is a being rather than a star: an entity from outside this world that came here and gave people powers, and whose gift carries with it the compulsion toward cruelty that has ruined nearly everyone who received it. Larcener proves to be another of the same kind, an earlier arrival who has been living among humans. David confronts Calamity, refuses the terms it offers him, and forces it to leave, which ends its hold over the world. Prof is recovered rather than killed: stripped of what was driving him, he is himself again, and the founder of the Reckoners is returned to them, though not undamaged by what he did while he was gone. David does not come through unchanged either, and ends the book with abilities of his own, which makes him precisely the kind of creature he spent his life hunting and the first test of his own argument that an Epic can choose otherwise. The Reckoners are left in a world that still contains Epics but no longer contains the force that made them monstrous, facing the work of rebuilding rather than the work of resisting.
