During a May 2013 Arizona vacation, Madeleine Martineau took seriously ill and found herself in the Phoenix Children’s Hospital, 5,000-plus miles from her native France and her London home. Diagnosed with high-risk acute myeloid leukemia, the 16-year-old spent seven months undergoing chemotherapy, clinical trials and treatments. With a weakened body and auto-immune system, she escaped the sterile hospital room by spending her hours … her days … her weeks … reading, watching TV and movies and surfing the Web.
