I really struggled with this book. The main character was very juvenile, and did not behave or speak as if she was in her 40s. It felt like she was a 13-year old girl (especially when she used phrases over and over again like "young hottie"). The dialogue and terms used were immature and made it hard to enjoy the conversations. It was very "tell" and not "show." I could not connect with either of the main characters, and did not find the storyline believable.
I would have liked to see more of the main character's personal development - the story had a lot of potential with respect to her therapy sessions after losing her husband, learning how to start over etc. Instead, the book was mostly Sylvie buying new things, giggling, and not knowing how to use a cell phone while trying to date a man who is significantly younger than her.
The main character was quite annoying, there was not a lot of depth or believability to the plot, and this book was not what I was expecting based on the description. Maybe would be better targeted to a YA audience.
