Twenty-five-year-old Linda Donovan has spent her life working for her father, Anthony, at Donovan and Daughter Exterminators in New York City. On the anniversary of her mother's death, her father makes his annual visit to his late wife's grave while Linda heads to a Park Avenue apartment building to work solo.

When she arrives, she finds the body of an elderly resident, partially eaten by rats. The gruesome death not only speaks poorly of the Donovans' exterminating services--it also points to foul play. When the cops show up, they demand to speak to Linda's father. But despite her efforts to contact him, Anthony has gone off the radar.

As he evades a possible murder charge, Linda's father records in five notebooks--and five damning acts--the story of how he met and fell in love with her mother, a previously untold history of familial abuse, tormented souls, and true love gone terribly wrong.
