Having read the Crown of Coral and Pearl duology and Luminous, I was certainly excited for another book by Mara Rutherford. The Poison Season was written during Rutherford's quarantine time during COVID, and the book reflects the way we all probably felt during that time of isolation. Being isolated on an island since birth, the dynamic between the island residents of Endla and those dubbed as "outsiders," there is certainly something to be said about staying on one place for an exponential amount of time.
