philosophical science fiction in the most literal sense

NECESSITY by Jo Walton

BY Jonathan Crowe

Necessity, the third and concluding volume of Jo Walton’s Thessaly trilogy, is not a book that can be read on its own. You really do want to read the first two volumes, The Just City and The Philosopher Kings, first. As I pointed out in my review of those two books last year, this series is philosophical science fiction in the most literal sense. It’s the story of Greek gods creating a real-world city based on Plato’s Republic as a thought experiment, designed to explore concepts of consent, volition and equal significance.
