Patient No. 7: One Man, Four Researchers, and the Quest to Cure Cancer (Kindle Single)

** Newly updated with a poignant epilogue **

In November 2011, after years in remission, 58-year-old Walter Keller had nearly lost his latest battle with leukemia. Desperate, the Keller family turned to University of Pennsylvania researcher Dr. Carl June and his small but determined band of colleagues to see if Walt could qualify for the group's radical, barely tested gene-therapy treatment for cancer.

In this gripping, emotional read, journalist and science writer Jason Fagone (Wired, GQ, New York Times Magazine) shows how what happened next — to Walt and a handful of other patients — may change the course of medicine and offer new hope to millions of cancer sufferers and their families.
