In the sequel to Daddy's Roommate (1990, not reviewed), ten-year-old Nick is the ""best man"" at the commitment ceremony of his gay father and his partner, Frank. Nick's mother, stepfather, and grandparents are delighted by the celebration, which takes place in a backyard and is officiated by a female minister. She asks the men to present their own version of vows before the multiracial attendees, who include other same-sex couples. The only dramatic conflict comes when the dog eats part of the wedding cake, an incident treated with equanimity and humor. In a book clearly intended to show such ceremonies as normal occasions, there is no suggestion that anyone might feel awkwardness. It is not so much bibliotherapy as a positive reinforcement of families, whatever their make up or configuration. A practical title for the parenting shelves, perhaps, rather than for general picture book collections, this book is less a literary effort than a work to reassure those in similar situations.
