The first few pages of Sinkhole recount the final moments of the author’s father’s life, as the author imagines they occurred.  Slipping away from the bedroom where his wife sleeps, her father writes a note and leaves the house for the last time.  It is nearly zero degrees in Minneapolis as he proceeds to the park where he usually walks his dog. All of this has been methodically planned: “My father chooses to die on the north end of the bridge.  There, the canopy is so dense that, from the street, the structure appears to grow from the hill. In the dim light spreading from the railings, the crown of its arch bestows darkness” (p.4).

 

Immediately following her father’s suicide, author Juliet Patterson is, naturally, overcome.  After the initial shock, she begins to wonder about her father’s motivation.  She realizes she did not know him as well as she had thought.  Theirs is a family that “rarely talked about important things” (p.9).  One of those things is that both her father’s father and mother’s father had also taken their own lives.  She begins to ask questions: “Who were these men?  What led to these deaths in my family?  What did my family’s history of suicide imply?  And what did it mean for my own future?” (p.10) The remainder of Sinkhole tells the story of how the author investigates the death of her grandfathers, a quest that takes her back to her family’s ancestral home in Kansas.   

One day, on an impulse, the author locates her grandmother’s abandoned house.  Like other properties in this part of the country where there were formerly mines, it has fallen into a sinkhole.  She sees the “terrifying alien world of a sinkhole” (p.111) as a metaphor for “a realm that I could not enter,” as she struggles to make sense of her family’s past. Eventually she undergoes a transformation and comes to terms with her loss.  The least she can do to break the cycle is to be honest about her family history with her young son.
