The book begins when Allie falls on her boyfriend Kevin, obviously trying to deceive. It appeals to Noah, a friend from high school. Comes the prom 20 years of their high school promotion (but that the Americans with their high school specials?) And found Olivia. In flashbacks, we know they were inseparable as children but we do not know why they no longer speak. Each has problems, but it's more focused on Allie. The memories but also people of high school age reappear, as if you've met the meantime had little hold on this small group. You want to know how the story will end this and why Olivia and Allie no longer speak for 20 years. The book reads pretty well. But it could be more fluid, Chapters begin with cosmetics slogans which we do not always see the connection with the story and it's a nice book but there is much funnier and more exciting.
