The setting is North Brother Island in New York. This place actually exists and you find some interesting information online about the medical facility there as well as info about Mary Mallon, aka Typhoid Mary. The author incorporated Mary Mallon in as a character who is quarantined at the facility due to her perceived illness. She interacts with our main character Cora.
The story involves generations of doctors in the Gettler family and spans over a 100 year period. There is more of a horror element to the experimentation the doctors perform on Cora and through it all, Cora lives alone on this island for decades. Cora's blood has qualities which make her immune to disease. Medical ethics are certainly in question here.
The back and forth chapters in the different timeframes was confusing at first. The book starts with Finn Gettler sneaking onto the island and seeing Cora. He is well aware of his father and grandfather's medical research but he doesn't know of the heinous experiments performed on this woman. There are surprises about Finn's family and while I did finish the book, there were some times I almost made it a DNF and moved on.
If you are engaged with the story then you'll be pleased to know there will be a followup book. I personally won't be looking to continue the storyline.
