"This is a sterling end to a rich, concept-driven series. This trilogy finale will thrill readers who want thoughtful, inventive fantasy powered by ideas." - Booklife Reviews (Editor's Pick) "Strong characters face a maelstrom in this intense, intellectually rigorous fantasy series finale." - Kirkus Reviews Recommended Read "I highly recommend the Dynamicist trilogy, and Knight in Retrograde in particular – Hunt has crafted something truly special here." J. Scott Coatsworth, Liminal Fiction Would you trade uncertainty for stagnation, chance for god, invention for inertia, thought for dogma? Four years have passed since the events of Dynamicist and war is on the horizon. Robert, Koria, Eloise and Gregory went to the New School, hoping to change the world. They thought that mathematically based dynamics, the enlightened age's answer to wizardry, would give them the power to make everything better. Their hopes were naïve. Protestors are condemning the creation of a new vaccine. The city is seeing a series of hangings; is it murder or sacrament? The cloaked man is back stalking students. The long-absent demons Skoll and Hati reappear and begin slaughtering whoever they meet. But the real question is, will Nimrheal return? If he does, who will die first? Uncertainty is inspiring fear, and inventions are not making the world better, only more complicated. The terrified civilians don't want dynamics and reason. They want the word of Elysium and the return of the Methueyn Knights. Koria fears the world faces an awful conundrum: that if the Knights return, Nimrheal will stay. Will Robert, Koria, Eloise and Gregory choose to transform into angelic knights or, at the cost of such heavenly communion, instead banish Nimrheal? What price will be paid? If a new Methueyn Knight rises, will the age of invention disappear forever?
