Gregory is the author of several novels, including the best-seller Wicked, which inspired the Broadway musical. Many of his books, he says, carry a common theme. "I tend to write stories about characters who have difficulty at the beginning of their lives," he says.

Gregory says he faced his own difficulty growing up. His mother died in childbirth, a tragedy that he says influenced his decision to adopt. Andy was also inspired by his mother, who died about 10 years ago. "In the final six months, when we spent a lot of time together, that was what turned me around about adoption," he says. "It became more and more evident to me that she had given so much and I wouldn't be here if not for her. I thought, 'Now it's my turn to do this for some children of our own.'"
