Special thanks to my fabulous wife Thu-Hằng Trần, who has now survived two seemingly endless writing projects with me—my doctoral dissertation in the mid-’90s, and now this book. I rarely say enough to her about her support and how much I value her. I hope that this acknowledgment helps to make up for that. Anh vẫn còn yêu mình, y’know?
