You can look at the cover to see in two seconds that this isn't going to be deep, dark, or life-changing. However, it was a little bit more than fluff. The characters have a few moments where good advice is given, or when a little light bulb goes off, and they realize something about their motives. For example, Esmie discovers that she is neglecting her dad's feelings, in her hunt-of-sorts for a new mom -- she was only considering whether she liked the potential new mom, and not taking into account what her dad thought. And their nanny has a lot of the best lines, urging the dad out of his comfort zone and not letting him remain resigned to be lonely forever.
Listening to this book was fun because of the British English, and also the French accent of the nanny. My kids would often try to imitate what she said.
