Ashby’s second novel, a sequel to her first, is engaging and better written than her debut, but it doesn’t address many of the flaws of the original. Ashby’s novels are set in a universe where humanity has created human-like robots, called “vN,” designed to carry out the tasks that human beings are no longer interested in undertaking. The technology was originally developed by New Eden, a cult that ostensibly wanted to create companions for all the sinners who would be left on Earth after Judgment Day.

Madeline Ashby’s vN chronicles the life of Amy, a sentient vN-model robot born into a mixed robot-human family. Amy’s human father has slowed her rate of growth to that of a human child, in hopes of integrating her seamlessly into human society, but when Amy turns five her maternal grandmother, Portia (who is a perfect copy of Amy and her mother), shows up and tries to steal Amy away.
