The Hundred Secret Senses Tan, Amy

Olivia's half-sister Kwan won't shut up about yin people — ghosts only she can see, remnants of her past life in 19th-century China. It's exhausting. But when Olivia's marriage crumbles and Kwan drags her to a remote Chinese village, the boundary between past and present starts to blur. Amy Tan weaves two timelines: Olivia's contemporary California and Kwan's memories of being a servant girl during the Taiping Rebellion. What begins as sibling comedy becomes something stranger and more magical — a story about belief, belonging, and the ways the dead refuse to stay buried. Tan's prose has weight and humour in equal measure. For readers who like their family sagas with a supernatural edge, or anyone who's ever had a relative who sees too much. Goodreads holds it at 3.8 stars across 45,000+ ratings.
