On the surface, this book is about alien invasion; the Seep is an alien entity that introduces itself into the very bodies and minds of humanity, attempting in its alien way to fix humanity’s problems. In order to stop humans from misusing resources and destroying the world, it gives people the ability to sense the entire life cycle of plants and animals by mere touch, globally increasing empathy and collective responsibility. Humans also become able to enact extreme physical changes on their bodies, and it’s the decision of Trina’s wife Deeba to do so that sends Trina into a spiral of doubt interrogating herself, the Seep, and the utopia it claims to provide. I liked the fact that Trina was trans, which meant that she’d already made her own decisions about her body and her fate long before the Seep showed up, and gave her a good foundation to be cynical about its promises.
