The Beloved Darling of the 1970s

After a peaceful death at the end of her natural life, Zisu unexpectedly received a welcome package for new arrivals in the underworld. It sent her from the twenty-first century into a miserable period novel. She was just about to leave a bad review when she realized this world was a mash-up of two novels, and her uncle and aunt were the male and female leads. What did that mean? It meant she could coast to victory! This definitely deserved a five-star review!
