Welcome to Unknown Pleasures, a food stand in Taipei's night market named after a Joy Division album, and also the location for a big-hearted new mystery set in the often undocumented Taiwan.

August is Ghost Month in Taiwan—a time to pay respects to the dead and avoid unlucky omens. Jing-nan, who runs a food stand in a bustling Taipei night market, isn't superstitious, but this August will haunt him nonetheless. He learns that his high school sweetheart has been murdered—found scantily clad near a highway where she was selling betel nuts. Beyond his harrowing grief, Jing-nan is confused. "Betel nut beauties" are typically women in desperate circumstances, but Julia Huang was high school valedictorian, and the last time Jing-nan spoke to her, she was far away, happily enrolled in NYU's honor program. The facts don't add up. Julia's parents don't think so, either, but the police seem to have closed the case without asking any questions. The Huangs beg Jing-nan to do some investigating—reconnect with old classmates, see if he can learn anything more about Julia's last years. Reluctantly, he agrees, for Julia's sake. But nothing can prepare him for what he is about to learn, or how it will change his life.
