On March 27, 2015, an admired brother hits send on an email asking six siblings to offer tissue samples for medical testing. Less than a week later, while lying in a hospital bed at Walter Reed Medical Center, recently retired U.S. Army Lieutenant General William J. Troy calls his youngest brother to ask, “Are you willing to save my life?”

In an instant, the urgency of life and death, the confusion of unfamiliar science, the mysteries of chance and fate, and the impulse to probe the events of an extraordinary life, unfold in the heart and mind of a younger brother 1000 miles away.

Stem Cell - a memoir, explores the anxiety, conflict, and vulnerability of two brothers as they plunge unwillingly into the complex and sometimes comical realities of cutting-edge medical science and recognize the vivid everyday blessings that forge the story of their lives.
