I'm always open to intriguing medical fiction, and while I hadn't read a book by Hawley in the past, this one drew me in. Dr. Luke McKenna is a pediatric emergency room doctor whose secretive past in the U.S. military catches up to him first when he assault's a patient's father and again when he suspects a cover-up in the death of a young boy brought to his L.A. hospital direct from Guatemala. The assault of the father seems like a minor plot compared to the surroundings of the Guatemalan boy's rapid demise, but it serves to discredit McKenna with authorities as he looks into the child's death. With research help from his colleagues at the hospital, McKenna finds the boy's symptoms to be puzzling in that he died of respiratory distress, but his lung tissue showed none of the usual signs of suffocation. What little progess he makes often leads to dead ends when the boy's body is quickly returned to Guatemala before an autopsy can be done and other samples and records disappear too.
Concurrently, the author tells the story of a man known only as Calderon, who also served with McKenna on the secret team and seems to have an axe to grind with him, yet it is the boy who is Calderon's focus and McKenna's involvement seems incidental. Clearly, Calderon either knows what happened to the child or is working for someone who does, but the bottom line is it must be covered up, and quickly. Hawley introduces a whole host of other characters in telling the stories of McKenna and Calderon, and while some are clearly on one side or the other, many of these characters shift over time, that until the book wrapped up, I couldn't tell who was good and who was bad.
The book was very fast-paced, taking place both in L.A. and Guatemala, but not so much that I lost track of what was happening. The science behind it was solid and did leave me with a 'what if?' feeling by the end, which is a sign of good modern science writing, that readers believe the events are not outside the realm of possibility. What also helped was that the disease process was immunological, dealing with natural killer T-cells and apoptosis, which is part of what my job involves so I had a better understanding of it than the science advances proposed in other fictional works.
My lone disappointment with this book was finding out that it's the author's only work to date (thus the reason I'd never read his books in the past). He developed strong characters who could continue on in future works, and I'll have to keep watch to see if another book comes out in the near future, because it's definitely one I would be interested in reading.
