⭐️⭐️⭐️⭐️⭐️ ooooh, I loved this one. It mostly takes place on a currently abandoned island near NYC from around 1900 up till 2007. The island once housed a hospital for people suffering from measles, typhoid, etc. It’s about the ethics of medical experimentation, Nazi war crimes, deadly viruses and epidemics, vaccines and cures, and family secrets and loyalty. It’s a heavy book and parts are dark, but I really, really liked it.
