A good story, but told in a mediocre manner. 
 It's the tale of a very lopsided friendship between two women, Rachel and Darcy, which goes awry when Rachel (the BFF who constantly gets the short end of the stick in their relationship) falls in love with Darcy's husband-to-be and isn't sure if she is willing to give him up and let Darcy win for the umpteenth time. 
 And, as I said, STORYWISE, it's GOOD. The prose is also fairly engaging, getting us into the main character's head in a solid, sympathetic manner, but this book has a crippling Achilles Heel. Frankly, it's that the dialogue is HORRID, and at times unrealistic and clunky. I just had a hard time believing it was actual conversation half the time. Oddly enough, the movie version which doesn't even HAVE Rachel's narrative to back it up, and has to RELY almost entirely on its dialogue, did a better job of making it work than the original novel does! 
 I did like the ending, though, how we see Rachel both stick up for herself and win, but also have to suffer the less than pleasant consequences of that choice. (view spoiler)[ Not only does she lose Darcy as a friend, she also has her parents who don't know the whole story miffed at her for "stealing a man from a lifelong friend". So her ending is bittersweet and oddly satisfying. (hide spoiler)] 
 Still the dialogue irks me so much, I just CAN'T give it more than three stars. 
 I recommend this book to anyone who likes friendship stories/Genre Women's fiction. Just be prepared to have to overlook some VERY lackluster character conversations and you'll probably find a lot to like about it!
