What is the name of this book please?

If you can't find it here, post again on the "Booksleuth" forum of abebooks.com, but make your heading descriptive, for example: "woman searches for lost love on Facebook, social media".

Then in the section below the heading, you should give ALL the information you can remember about the rest of the plot, when you read the book (and don't just say "when I was in high school" because how can people know what YOU were at school?) and what country you were in.
