If you could live for hundreds of years, if not, forever, would you want to? In Suicide Club, those who deserve it are given immortality. In exchange, they have to take good care of their health — eat well, exercise and all that jazz. What I liked about this premise was that it plays on our contemporary obsession with health and wellness. Food diet movements abound from "clean eating" to keto to paleo, claiming to detox, strengthen the immune system, etc. Rachel Heng pushed these ideal to the extreme in her futuristic science fiction novel set in New York City.
