Ever imagine what it would have been like if one of your parents had been gay and you hadn't found out until you were 12? That's the background of Alison Wearing's tender memoir, Confessions Of A Fairy's Daughter ($24, Knopf). Her dad eventually acknowledged his orientation in the 70s - in small-town Peterborough no less - and struggled to be out and proud and a devoted father, a rare combination in those times. Aided by his letters and journal entries, Wearing tells not just his coming-out story but hers, too, as the child of a gay man. Wearing's performing her one-woman show based on the book at the Arts & Letters Club June 15 and 16.
