As a young girl, Becky is forced to hide from phantom Nazis, subjected to dental procedures without pain medication, and torn from her mother again and again. Growing up in the shadow of her father's PTSD, she wants to know what is wrong but knows not to ask. Her father won't talk about being a Timberwolf, a unit of specially trained night fighters that went into combat first and experienced a 300 percent casualty rate. He returns home with thirteen medals and becomes a doctor, but is haunted by his past. Seeing only his explosive and often dangerous personality, Becky distances herself from the man she wants to love. Yet on the eve of his ninetieth birthday, when Becky looks at the vulnerable man he's become, something shifts, and she asks about the war. He breaks seventy years of silence, offering an unfiltered account of war without glory and revealing the extent of the trauma he's endured. She spends the next several years interviewing, researching, and ultimately understanding the demons she inherited. Because his story is incomplete without hers, and hers is inconceivable without his, Ellis offers both, as well as their year-long aching conversation marked by moments of redeeming grace. With compassionate, unflinching writing, Little Avalanches reminds us that we are profoundly shaped by the secrets we keep and forever changed by the stories we share.
