A dying man. A microbial offer. A second life neither asked for. When ninety-two-year-old Elias Crane begins hearing voices from within — not hallucinations, but a polyphonic microbial chorus — he is given a choice: surrender death in exchange for symbiosis. As his body renews itself under their guidance, Elias rediscovers love, memory, and a haunting vitality that blurs the line between human and host. But as the transformation deepens, so do the questions: Where does he end? Where do they begin? And what happens when the woman he loves starts hearing them too? Told in lyrical fragments, intimate diary entries, and microbial mythologies, A Body of Histories is a speculative meditation on aging, identity, desire, and the strange beauty of living organisms who just want to be remembered.
