Litany of Sorrows is a story of passion, betrayal, and the devastating cost of complicity.

It begins when Karl von Richter, a handsome young German with a sinister future, is injured skiing in the Italian Alps. Nursed to health by a beautiful woman, Katrina Amorino, the two fall in love. Unaware that Germany is preparing for war, she naively leaves northern Italy and moves to his home in southern Germany. But days before she arrives, Karl is drafted into the Nazi SS officer training school, where he is radicalized. As Karl descends into the machinery of the Final Solution to build camps and kill Jews, Katrina hears about his horrific deeds, flees for her life, and is haunted by impossible choices and a son she may never see again.

As the war ends, Karl’s last Nazi task is abandoned, and he heads home, but finds his parents dead, and Katrina and their child missing. Karl's conscience begins to reawaken while he searches for Katrina, who is hiding in fear and agonizing over her impetuous decisions, which become her litany of sorrows. Decades later, the consequences of their love—and their separation—ripple outward in ways neither could have foreseen.

From forbidden love in the Italian Alps to high-stakes international investigations decades later, author Peter J Marzano weaves the Brian O’Sullivan series together with emotional depth, historical intrigue, and relentless suspense. And at the heart of the award-winning series lies a single question: How far will we go to uncover the truth to heal from it? Together, these novels form a sweeping narrative about the weight of history, self-inflicted damage by poor choices, and the resilience of the human spirit. From wartime Europe to modern-day investigations, the heart-wrenching Brian O’Sullivan series explores how love, guilt, and legacy shape generations—and how the past never stays buried for long.
