Book excerpt: Avery Bardot steps off the plane in Rome, looking for a fresh start. She's left behind a soon-to-be ex-husband in Boston and plans to spend the summer with her best friend Daisy, licking her wounds--and perhaps a gelato or two. But when her American-expat friend throws her a welcome party on her first night, Avery's thrown for a loop when she sees a man she never thought she'd see again: Italian architect Marcello Bianchi.
