== Description ==
Lucas Arrowood is walking to school on his first day of kindergarten when he meets Dalton Churchill—a boy who stops and helps him tie his shoe. He knows from that moment he is going to marry that boy one day. “Boys can’t marry other boys,” his mother explains, but that doesn’t stop Lucas. He knows what he wants.
He and Dalton become best friends. And then, no matter how much he resists, Dalton falls in love with Lucas. Dalton’s very conservative family can’t accept that their boy loves another boy, but finally Dalton stands up for love and for Lucas. Still, he declares he won’t marry Lucas until it is legal everywhere. He hates the “commitment ceremonies” gay men have. They aren’t the real thing. Why bother?
So Lucas waits for his day. The day same-sex marriage finally becomes legal and he can be joined forever with the love of his life.
