Multiple Hugo and Seiun Award-winning author Allen M. Steele returns once more to the Moon—and beyond—for the concluding chapter of the rousing space mystery that began with “Lemuria 7 Is Missing” (Asimov’s May/June 2023, which won last year’s Readers’ Award for Best Novella) and “The Hunt for Lemuria 7,” published earlier this year in the May/June issue.
