----------------------------------------------------------------------------------------------- LIKE A TWISTING DOUBLE HELIX OF DNA, these two satisfying stories of compelling and complex father-daughter pairs entwine with life-altering surprises. They bring compassion, humor, and understanding to the question of whether it is ever too late for paternal instinct. EACH YEAR THOUSANDS OF MEN father children later placed for adoption or donor-conception. Some of them thought they would forget. Some claim they never knew. There are several million of these secret fathers in the United States alone - in The Birth-Fathers' Club Series eight of them are about to get a knock on the door - as changing times catch up with them and with adoptive parents, recipient parents, anonymous donors, and the rest of our beloved ancestors.
