ACKNOWLEDGMENTS

They say publishing a book is like having a baby, but it takes longer and hurts more. Appropriately, this “baby” has far more than two parents. There would be no Sex at Dawn without the insight, encouragement, and patience of our families, especially Frank, Julie, and Beth Ryan, Joana and Manel Ruas, Alzira Remane, Celestino Almeida, and Danial Jetha.
