“Agency,” Mr. Gibson’s next novel, which Berkley will publish in January. The story unfolds in two timelines: San Francisco in 2017, in an alternate time track where Hillary Clinton won the election and Mr. Trump’s political ambitions were thwarted, and London in the 22nd century, after decades of cataclysmic events have killed 80 percent of humanity. In the present-day San Francisco setting, a shadowy start-up hires a young woman named Verity to test a new product: a “cross-platform personal avatar” that was developed by the military as a form of artificial intelligence. Meanwhile, characters in the distant future are interfering with the events unfolding in 2017, through technological time travel that allows them to send digital communications to the past.”
