Cardiologist Dr. Sandeep Jauhar is brutally honest in his memoir about his deeply personal journey caring for his father with dementia. After several false starts, he admits there were experiences he didn’t want to revisit and share. His need as a doctor to get answers to his questions about what was happening to his father’s brain was the motivation to put his findings into a book that reads like a novel but also offers clarity to other caregivers.
