Calvin is the son of a missionary family, and their trip to Portofino is the highlight of his year. But even in the seductive Italian summer, the Beckers can't really relax. Calvin's father could slip into a Bad Mood and start hurling potted plants at any time. His mother has an embarrassing habit of trying to convert "pagans" on the beach. And his sister Janet has a ski sweater and a miniature Bible in her luggage, just in case the Russians invade and send them to Siberia. His dad says everything is part of God's plan. But this summer, Calvin has some plans of his own . . . Portofino is the prequel to the noted trilogy that includes Zermatt. A huge bestseller, Portofino has been translated into seven languages.
