Air Botany is a futuristic love story involving interspecies communication and a dream world that evokes a range of indigenous beliefs. The story begins in 24th-century California, where Dr. Duckworth, an archaeologist researching the 21st century, meets Mia, a linguist who communicates with plants and animals. Mia is an advocate for Future Seed, a plant that has transformed human consciousness in the 24th century. Duckworth has recently stopped consuming the seed as part of his research, which leads Ron White, a colleague and systems theorist, to accuse him of subversive activities. The narrative parallels the story of Milo, a young boy coming of age in 2015 rural Vermont where his father is growing the precursor to Future Seed. As the story unfolds, Milo is reincarnated into the future as Duckworth and Mia's son, becoming the first member of a new human species.
