"Serum" by Christopher McDonald was a quick, entertaining read for me. A medical thriller you could say about Dr. Lacy Miller, a Chief Medical Examiner, who develops a serum that allows murder victims to "talk". So unsolved murders could be a thing of the past - or so it seems! The idea behind this book is one that I think is very interesting. The story pulls you in and takes you for a fantastic ride with an array of interesting characters that keeps you turning the pages. Speaking on the characters: The author walks a thin line with character development. If he had spent too much time on character development, he would have been hindered developing the plot. I thought he exhibited a balance that allowed him to tell his story very well indeed.
