The Mother Daughter Book Club by Susan Patterson & James Patterson

Between their busy lives and their far-flung residences, 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 finally gather again, this time 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 trademark "Night of Secrets." 

These friends, and sometime rivals, are close readers--of novels, memoirs, and of each other. But as the years and the distance cast shadows and doubt, confidences and sympathies turn into surprising revelations.
