Now in paperback, the eighth book of the bestselling Rivers of London series returns to the adventures of Peter Grant, detective and apprentice wizard, as he solves magical crimes in the city of London. Peter Grant is facing fatherhood, and an uncertain future, with equal amounts of panic and enthusiasm. Rather than sit around, he takes a job with émigré Silicon Valley tech genius Terrence Skinner's brand new London start up—the Serious Cybernetics Company. Drawn into the orbit of Old Street's famous 'silicon roundabout', Peter must learn how to blend in with people who are both civilians and geekier than he is. Compared to his last job, Peter thinks it should be a doddle. But magic is not finished with Mama Grant's favourite son. Because Terrence Skinner has a secret hidden in the bowels of the SCC. A technology that stretches back to Ada Lovelace and Charles Babbage, and forward to the future of artificial intelligence. A secret that is just as magical as it technological—and just as dangerous.

“One of the most intriguing future cities in years.” —Charlie Jane Anders “Simmers with menace and heartache, suspense and wonder.” —Ann Leckie A Best Book of the Month in Entertainment Weekly The Washington Post Tor.com B&N Sci-Fi Fantasy Blog Amazon After the climate wars, a floating city is constructed in the Arctic Circle, a remarkable feat of mechanical and social engineering, complete with geothermal heating and sustainable energy. The city’s denizens have become accustomed to a roughshod new way of living, however, the city is starting to fray along the edges—crime and corruption have set in, the contradictions of incredible wealth alongside direst poverty are spawning unrest, and a new disease called “the breaks” is ravaging the population. When a strange new visitor arrives—a woman riding an orca, with a polar bear at her side—the city is entranced. The “orcamancer,” as she’s known, very subtly brings together four people—each living on the periphery—to stage unprecedented acts of resistance. By banding together to save their city before it crumbles under the weight of its own decay, they will learn shocking truths about themselves. Blackfish City is a remarkably urgent—and ultimately very hopeful—novel about political corruption, organized crime, technology run amok, the consequences of climate change, gender identity, and the unifying power of human connection.
