Archer Magill has spent a lively five years of grade school with one eye out in search of grown-up role models. Three of the best are his grandpa, the great architect; his dad, the great vintage car customizer; and his uncle Paul, who is just plain great. These are the three he wants to be. And now there's a fourth: Mr. McLeod, the first male teacher in the history of the school.<br /><br />But in the midst of it all comes middle school and puberty. Archer doesn't see too far ahead, so every day or so a startling revelation breaks over him. He wonders how much change has to happen before his voice changes. Then a really big revelation comes: he's asked to be the best man at the wedding of two of his role models.<br /><br />Newbery Medalist Richard Peck tells a story of small-town life, gay marriage, and everyday heroes in this novel about a boy on his way to being the best man he can be.
