"Rachel and Eliza, a married couple planning to have a baby together with their friends Hal and Greg. The experience brings the women even closer together until one night Rachel wakes in great distress, believing that an ant has crawled into her eye - and Eliza doesn't believe her. With this event, the fault lines in Rachel and Eliza's fundamental ideas about their relationship are exposed, calling into question their willingness to truly accept and have faith in one another, and their future together. The story is told from the point of view of different characters in Rachel and Eliza's world (including the ant itself) and, inspired by Ward's fascination with scientists and philosophers and the way they use stories to discuss important ideas, uses 11 of the best-known thought experiments in philosophy as a device through which to talk about love."--Publisher description.
