Painful Joy represents five years of intensive research in the US, Poland, Sweden, Israel and Germany, seeking to unearth the real life stories of Sam and Frieda Friedman in order to discover their roots, recreate their lives and times and uncover both their remarkable journeys and painful secrets. Part memoir, part genealogical mystery and part history, the book is an absorbing, heartwarming and, at times, heartbreaking tale as readers accompany the author on his extraordinary exploration of the complicated relationship between two Holocaust survivors who meet in Sweden after their liberation, and experience the "painful joy" of a love too often touched by death.
