What does being a doctor really feel like? What is it like to get called out in the middle of the night to care for a desperately ill patient, to be the one everyone depends on? Bob Gilsen knows only too well. And what does a fifteenth century physician, who gets called out in the middle of the night in winter, possibly have to offer his patient? This is the beginning of The Book of Drachma, a novel of medicine, murder, fantasy, and self-discovery, set in two times and places. It is a novel for the curious, for those who really wish to know what it means to be a doctor, in this, as well as past ages. In Part One, Laminar Flow, readers find the two stories have a commonality that transcends the barriers of time and place, and leads to the two tales coming together under the watchful eye of the mysterious Drachma.
