Harry Kraus, M.D., may have been writing fiction since 1994, but his name is nowhere near as well-known as fellow Christian authors Ted Dekker, Tim LaHaye, and Jerry B. Jenkins. I think that's quite unfortunate, because Dr. Kraus is a wonderful author, as evidenced by "The Stain." It's partly an "ER"-style medical drama, partly a techno-thriller, and partly a "Monk" or "Murder, She Wrote"-esque mystery tale. All those parts blend together quite well, making a story that kept me wondering what would happen next. I don't want to give away the plot, so I'll just say this: Just when you think the story's ended, the epilogue adds an extra detail that will blow you away. As far as content goes, there were some graphic details, but that's to be expected, considering the subject matter. In short: This one was definitely a winner.
