Thomas Norman DeWolf, a Pomona native, and Sharon Leslie Morgan will speak at 2 p.m. at the church.
Together they penned "Gather at the Table: The Healing Journey of a Daughter of Slavery and a Son of the Slave Trade."
In the course of a 3-year period the authors traveled outside the country and to 27 states along with ancestral towns, courthouses, plantations and other historic locations.
They participated in conversations about the "lingering trauma of slavery and racism" and how it affected their lives and those of others in the United States, DeWolf said. The two met in a week-long class designed to help people understand the traumas resulting from the nation's slavery period and begin to build bridges that will bring blacks and whites together, he said.
A year later the two began a journey with the lessons learned detailed in their book.
The authors will give a presentation that will be followed by a discussion.
