What if a man lost his moral compass between right and wrong, good and evil, mental stability and insanity?

John Corbin has been investigating, catching, and convicting murderers, rapists, and pedophiles for twenty years as a Seattle detective. But lately, someone has been beating him to the punch and eliminating these vile criminals before he can apprehend them. John is learning that there is a thin line between innocent or guilty, good or evil, alive or dead.

By definition, a thin line is a very narrow division between two alternatives. Some being exact opposites, while others are separated by the narrowest of threads. This novel follows this definition to the letter. In life, many situations aren't just black or white. There is usually a modicum of grey to fill in the space. Who is right? Who is wrong? Who is good? Who is evil? Perhaps everyone at one time or another lies somewhere in the middle....

A Thin Line is a tale that will immediately draw you in and keep you guessing. A suspenseful psychological thriller with twists and turns that will toy with your mind and emotions, driven by a chilling narrative that builds the tension right up until its explosive conclusion.

Reader's thoughts:

                       "I’m tough to please, particularly in this genre: I have spent my life in legal education and scholarship, specifically teaching and writing on the law of evidence, and in particular, forensic psychiatric evidence. I approached A Thin Line with some skepticism. I am glad to say that this skepticism was entirely unwarranted. David Boiani’s story is well-constructed, and it is insightfully told. I have always held that the notion of being able “to keep one’s work out of one’s personal life” is preposterous, and Boiani’s John Corbin is “Exhibit A” that reveals this pretense. Boiani keeps a high-paced, linear-driving narrative pounding, diving off with many unforeseeable twists. But it was the numerous vantage points from which we see Corbin’s interacting humanity–with his family, with his broader relationships, with his philosophies–that kept me most-engrossed. I must also commend Boiani with his precise and well-developed research. Every evidentiary detail is scientifically accurate–and accurate in how the law would treat the evidence, by my evaluation. This requires a significant degree of mastery of the intersections of these multiple areas (each of which is complex and each of which requires mastery). A+. I will warn: this book is not for the squeamish. This is the raw, horrible, gruesome, human-as-a-horror truth of man’s depravity. I am surprised the book was not dripping blood as I held it. Nor is it for the intellectually lazy who do not want to be confronted with one’s ultimate questions. A Thin Line points up those not inquisitive. Very well done!"
                     "Wow. Are you friggin kidding me? Believe me when I tell you that you will say the same thing I did in my tagline, throughout this novel. This book is disturbing and mind-numbing, but guess what? I enjoyed every moment of it. These will be so many moments in this book where you will be on edge, as you can't wait to turn the page to see what happens next. This is the author's first book and boy did he make a splash. The pacing was fantastic. I also enjoyed how the author tied everything together at the nail-biting end. Disturbing stories can be highly entertaining... this is one of them!"

                      "You will need to leave the lights on. Reason number one: this book is going to creep you out. Reason number two: you will be up reading late into the night - you simply cannot put it down. The chapters are short and succinctly written with lots of action to move the narrative forward in a fast-paced manner. The plot twists will keep you guessing and the characters are easy to identify with: you will care about what is going to happen to them. Noir-ish in many ways, the story weaves gore and violence with love and sex, family life and friendship, mystery and police procedural and it all works together, resulting in a story that will stay with you for many reasons. If you like Dexter, Hannibal and Criminal Minds, get this book. Even if you don't - get this book. It's definitely worth it!!
