This was the first book that I read by this author. I found his plot and writing style thoroughly entertaining. By the early quarter of the book, I had trouble putting it down because I couldn't wait to know what happened next. I appreciated the fact that the plot wasn't far fetched and that it was authentic enough that it could really happen (which added to the fear factor for me). Also, the ending provided me with a sense of "closure," as the killer, his motives, and methods were revealed, and the author described the fates of each of the main characters. If you like medical thrillers, you will definitely like this book because it is engaging and well-written.
