Brannon’s Reviews > Mortal Engines > Status Update

I liked the imaginative premise, the world building, and the likable characters. It was a well written book. But that said, I found the moving, predatory city concept unbelievable in the long run. I know, it's more fantasy than science fiction, but still, if your going to invoke darwinism and a survival of the fittest concept, you need to stay true to that, and there's simply no evolutionary theory underpinning this.
