Bruno, who grew up in New York's Hudson Valley knowing little about her Dutch heritage, was shaken when a historian told her that her Dutch ancestors were almost certainly slaveholders. Driven by this knowledge, Bruno began to unearth her family's past. In the last will and testament of her ancestor, she found the first evidence: human beings bequeathed to his family along with animals and furniture. The more she expanded her family tree, the more enslavers she found. She reached out to Black Americans tracing their own ancestry, and by serendipitous luck became friends with Eleanor C. Mire, a descendent of a woman enslaved by Bruno's Dutch ancestors.

A Hudson Valley Reckoning recounts Bruno's journey into the nearly forgotten history of Northern slavery and of the thousands of enslaved people brought in chains to Manhattan and the Hudson Valley. With the help of Mire, who provides a moving epilogue, Debra Bruno tells the story of white and Black lives impacted by the stain of slavery and its long legacy of racism, as she investigates the erasure of the uncomfortable truths about our family and national histories.
