Virtually Normal: An Argument About Homosexuality .
By Andrew Sullivan
Knopf, 209 pages, $22
What would life be like if we were not allowed to marry? That is the question at the heart of Andrew Sullivan’s first book, Virtually Normal . In a sharp departure from the brash tone of the New Republic , the political weekly he edits, Sullivan here takes a sober look at the public debate over homosexuality and offers a moving, often lyrical, plea for the legalization of same-sex marriage.
