I was really enjoying this audiobook until about 60% but it gradually started to lose me and I found myself only listening to just get it over with. I love medical/science history and I think the Kean did a decent job exploring the ethics of medicine and its scientists. HOWEVER I could not take the (what felt like constant) podcast plugs by the author. I think it was even more jarring due to listening to it rather than reading physically. Maybe I could have ignored it better that way, but towards the end I swore if I heard one more plug I was going to lose it. 

Overall, I liked it. Not my favorite medical/science history book, but decent enough.
