Theo MacBain, master mason, divorced, lonely, follows some simple rules. Work hard. Keep the stones plumb. Don't hire a woman - she'll be trouble. But he breaks his rules when he agrees to take on Hanson Blair as an apprentice. First, she earns his respect by working hard. Then she arouses his protective instincts when he senses she is in trouble. And soon enough, she makes him forget the age gap between them. He falls for her. Hard. And there is no turning back. Should have stuck to his rules.
