EMILY GIFFIN 4 EVER! I didn't love it as much as Love The One You're With and I basically hated everyone in this book besides Tessa, Frankie and Jason but it was still so good and giffinesque.
Bonus: sneak peek of the next genius book which thrillingly promises to cover the sordied texting of tv execs, what to do when your boyfriend loves you but doesn't want to get married, and why long lost babies given up for adoption always appear on your doorstep when you are wearing your "coziest flannel pajamas"!!
