Will AI save humankind … or destroy it? Jessie Monroe, CIA's top spy, is back at Langley tracking down the culprit behind a mysterious leaked list of agent names and locations, including hers. There she meets the Human Interface Learning System prototype, Hils , who looks like a human…but he’s not. The advanced humanoid is the US’s newest entry in the robot race between the superpowers. While the humanoid tries to assimilate the vast amount of information on the internet—some real and some fake—he grapples with truth, love, and his own sexual orientation. Meanwhile, Jessie uncovers an even bigger plot, and discovers Hils is a key to the mystery…and much more. Jessie becomes “Juno Wolfe” again, on a rogue mission to take her unlikely team on a perilous journey to prevent World War III.
