In short, episodic chapters that move unpredictably and unchronologically through the years between 1956 and 2003, Nick Flynn tells us about his father, Jonathan Flynn--a man of many trades, a writer, an alcoholic with a prison record, a homeless person--and of his own life, which sporadically interweaves with Jonathan's. When Nick was six months old, his 20-year-old mother left Nick's father and made a meager life for herself and her two young sons. A string of her live-in boyfriends and one more failed marriage wound their way through Nick's young life, which was in the seaside town of Scituate, Massachusetts, "the second most alcohol-consuming town . . . in the United States" (77).

At 12, Nick is drinking beer; at 17 he is drinking to get drunk, sometimes with his mother, and smoking marijuana (and later doing other drugs). For years Nick's father "had been manifest as an absence, a nonpresence, a name without a body" yet, "some part of me knew he would show up, that if I stood in one place long enough he would find me, like you're taught to do when you're lost. But they never taught us what to do if both of you are lost, and you both end up in the same place, waiting" (24).

The place where Nick and his father "end up" is the Pine Street homeless shelter in Boston where 27-year-old Nick is a caseworker and Jonathan Flynn appears, a few months after being evicted from his rooming house. Reluctantly, Nick gradually acknowledges his father's presence in the shelter, and gradually, during the next 15 years, reconstructs the lost years through conversations with his father and his father's acquaintances, letters, and manuscript excerpts. The title of the memoir is what Jonathan Flynn mutters at night, when he is looking for a place to sleep (205).
