I read the orignal book by Emily Giffin when it first came out, but when was that? 2003? 2004? 2005? But it has been awhile. Therefore, I cannot tell you for sure how much the movie followed the book, but I am sure they took some liberties with the story. Nevertheless, I loved it!
Target has the book so I might want to re-read it. Here is the story in a nutshell without giving anything way!
It is about 2 best friends, Rachel and Darcy. Rachel is the serious brunette who went to law school and Darcy is the bubbly blonde and the one for whom things always seem to be perfect. She always gets what she wants. She is not as serious or as smart as Rachel. Darcy is engaged to Dex whom Rachel went to law school with.
Rachel had a crush on Dex in law school and he on her, too--but neither one knew how the other felt (although the chemistry was undeniable!), and Rachel never felt beautiful enough for Dex. So it was Darcy who ended up with Dex.
Fast forward to present day and Darcy is throwing Rachel a surprise 30th birthday party...and that is when things between Dex and Rachel start to heat up again!
Anyhow I won't spoil anything for you. It is a lovely movie & a delightful way to spend a few hours--although my husband might not agree with that!
