Yet I found the sci-fi plot in need of unpacking. I wanted more tech explanation. Why did the “grams” have to believe they were real? Why was Gregor, a nice boy, so keen on selling his sister for science? Why did Adrien’s mother suffer the almost comically awful husband? I found myself craving more Cora and Adrien, less science hokum. Ditch the “grams” and bring them back!
