I normally don't read medical thrillers, but this was a great book.
Chris Collins' father, Wayne, has just come back into her life after almost thirty years. He has come asking for a part of her liver. He is a recovering alcoholic in need of a liver transplant. Due to his alcoholism, he can't be moved up in the list if his need becomes greater. He has heard that a relative can give him a portion of their liver and that portion will regenerate in the donor and the portion given will grow into a full liver for him.
Chris is not sure what she thinks of her father's return, but she knows she can't give him a portion of her liver. Instead she is able to get him into a new program that will transplant a genetically altered pig's liver into a human.
The transplant goes very well. Then Wayne has a fever. There are so many precautions taken to prevent from infecting Wayne or anyone else, but still they keep a close eye on him. He gets well quickly and they figure all is well. Matter of fact, things seem to be going extremely well, better than expected.
When some nurses that took care of him die, they start looking into whether this could be related to the transplant. Then some more people die. They can't figure out how these people tie back to the transplant.
Chris feels responsible and works hard at investigating the various deaths, including looking into where their lives might have intersected.
The pace in this book is great. It keeps you wondering what will happen next. I found it difficult to put down.
The characters interact well and there is enough uncertainty that you can't easily figure out too soon what is going on. It is very well written.
I recommend this book.
