Raised in a family he bore little resemblance to, Randy was jokingly referred to as "the milkman's son." This warm and candid memoir chronicles the unraveling of a family secret, which begins with Randy's dad having dreams about deceased relatives urging him to complete their family tree. Randy agrees to help with the genealogy, but after his searching leads to a dead end, he takes a commercially available DNA test. The results reveal a possible genetic match to a sister, which begins a familial quest that forever changes the author's life.

Featuring a cast of vivid characters, richly drawn from two distinct families, The Milkman's Son reveals one man's family tree, pulling back layers of new information as he gets closer to the truth—a biological father, siblings, and family members he never knew about.

This is a story of accepting, forgiving, reuniting, and, most importantly, it's about the bonds that connect us and the unconditional love that makes us feel like we belong.
