Who wouldn't want to go on a trip around the world? When best-selling novelist Sparks receives a travel brochure from his alma mater, Notre Dame, he thinks, "If not now, then when?" and asks his brother to join him. They both have family obligations, but this sounds like the trip of a lifetime, and as the reader soon finds out, they both need to relax. As they journey to faraway places, the brothers reminisce about their unusual childhood.
