"You deserve this," he continued. "People are evil to the core. That's what the Epics prove. That's why you're dying out..."
In Steelheart, we were introduced to the Reckoners. They are the sole resistance to the Epics, normal people who developed super powers after the appearance of a star called Calamity. David joined the Reckoners to kill Steelheart, the Epic who killed his father.
The second book, Firefight, brought new revelations about the Epics. David encounters Megan again, AKA Firefight. Prof, the leader of the Epics (And also an Epic), is completely overtaken by his powers. David meets Calamity, and it turns out that Calamity isn't a star, but an Epic. There is a whole plan to turn David into an Epic by throwing him at Calamity in hopes that his initial transform will lead him to killing a bunch of people, but he ends up resisting. Megan was almost killed after being confronted with her weakness, but they figured out that by confronting the fear she could overcome it.
Calamity shows the Reckoners after the devastating events at the end of Firefight. Quick, spoilery recap: Prof went full-on Epic. The remaining Reckoners keep on keeping on. David takes Tia's recon position (Tia was Prof's girlfriend, they haven't heard from her and assume she is dead) as they raid a weapons factory. The factory is run by Prof's old friend Knighthawk, who ends up helping them. Prof, now calling himself Limelight, has taken over a city made of salt that constantly moves around, collapsing and rebuilding itself.
David and the Reckoners plan to confront Limelight with his fears to get Prof back. Knighthawk manufactures tech that can replicate Epic powers through DNA. The Reckoners simply have to get Limelight's DNA, send it to Knighthawk, wait for him to create the tech, then use Limelight's powers against him. Since Prof was most afraid of using his powers and being overwhelmed, he should hypothetically stop being an Epic jerk and turn back into Prof.
They get an unexpected ally when the Epic Larcener shows up at their hideout. Limelight has been looking for him because of his power to steal abilities and make Epics ordinary again. Limelight doesn't want to make friends, if you catch my drift.
There are, as always, some twists and turns along the way. Overall, I found Calamity to be a pretty satisfying conclusion to the series. Steelheart hooked me from the first sentence, and I've enjoyed my time in the world of the Reckoners.
