The Mother-Daughter Book Club―four longtime college friends and their five daughters―more often discuss the books on their nightstands via 2 a.m. texts than in-person meetings. And maybe it’s just as well, after what happened at their last get-together… So it’s an emotional reunion when they regroup on the spectacular shores of Italy’s Lake Como. Sightseeing excursions, reminiscing fueled by “Como-politans,” and a hint of vacation romance all build toward the book club’s “Night of Secrets.”
