Interesting for several reasons. These include
1) Located in Kansas City; I have lived within 100 miles of this my whole life. Areas of the book are familiar and some history to Armour building and surroundings.
2) The subject of organ transplant by individuals selling their organs is a controversial issue. Having been a recipient of a heart transplant I know the pre, during and post transplant procedure to safely have a transplant and follow up.
3) The characters were unusual-- a 70 something police officer and his long lost brother in law who is a McGuyver want a be and waiting for a kidney transplant.
4) Humor

It is pretty far fetched that a ring would set up a illegal transplant center in Kansas City, find individuals offerig to sell organs and families needing black market organs to pay high prices for transplants. Knowing what is involved in the process before, during and after a transplant makes me ask all kinds of questions. For instance, afterwards, how do the recipients have the necessary follow up, medicines, testing for rejection, etc. Any post transplant treating facility would want to have the medical records of when and where the surgery was performed, etc. One doesn't just have a transplant and is cured. It is a lifetime of challenges afterwards.

If I just read this story it is enjoyable, but it is truly impossible to believe it could happen.
