The Echo Wife (Hodder, £17.99) begins as scientific superstar Evelyn discovers that her husband has been cheating on her … with her own clone. Evelyn has come up with a way to grow adult clones from a DNA sample, capable of speech and understanding, the original’s personality imprinted on their brains. Legally they are not people, merely disposable tools. The horror of a society that would allow this is never touched upon, nor are there any moral or economic arguments made for their use. The plot is even more full of holes: Evelyn is a genius, yet her husband (a mere academic) not only runs with her idea, he manages to secretly produce her clone in his spare time.
