Sleeping Arrangements by Madeline Wickham (2008)

An enjoyable light read about two families who are forced to spend their vacations together in a mutual friend's villa in Spain. Turns out they are quite connected. Chloe is hoping to relax with long time partner Phillip, who is in danger of losing his job, and her two sons, one a sulky teen. Hugh, a busy executive is hoping for some fun time with high strung Amanda and his two small daughters. But Chloe and Hugh were an item 15 years ago. I liked looking a relationships that have been going on for a while, and the challenges they face. The punky nanny adds delightful color to the story.
