Having joined A. G. Hayes in this fifth Koski & Falk thriller, I have several times been asked if one has to read the others in the series in order to take full pleasure from QUANTUM DEATH (Savant 2016). I'm pleased to say, no. Mr. Hayes' style is such that one can begin with any one adventure and then expand before or after without loss. Still, there is the detail of their "growing" relationship, beginning with WHO'S KILLING ALL THE LAWYERS? (Savant 2011) through QUANTUM DEATH and, I daresay, well beyond. As a series goes, this one is uniquely suited to "dropping in" wherever and whenever the reader chooses. Me, I preferred to start with WHO'S KILLING ALL THE LAWYERS, then work my way through THE JUDAS LIST (Savant 2012), IMMINENT DANGER (Savant 2013), and THE CHEMICAL FACTOR (Savant 2015), and am pleased to say that the storyline is entirely cohesive. After much discussion with Mr. Hayes, I can say with authority, that the series is intentionally made that way. Enjoy, wherever you decide to jump in.
