To: Jane Harris Fr: Claire Harris Re: YouHi, honey! It's me, Mom. I know it's a big secret that your friend Holly and her boyfriend Mark are eloping in Italy, and that you and Mark's friend Cal Langdon (the handsome New York Journal reporter with the big book deal) are going, too, as their witnesses. But I just saw Holly's mother at the Kroger Sav-On, and I thought I'd warn you: She doesn't seem to like Mark very much at all. Just wanted to let you know.PS I don't understand why you don't like that nice Cal Langdon! He seemed so smart when I saw him being interviewed on Charlie Rose. And so handsome!PPS Don't forget to wear a sweater!Cartoonist Jane Harris is delighted by the prospect of her first-ever trip to Europe. But it's hate at first sight for Jane and Cal Langdon, and neither is too happy at the prospect of sharing a villa with one another for a week—not even in the beautiful and picturesque Marches countryside. But when Holly and Mark's wedding plans hit a major snag that only Jane and Cal can repair, the two find themselves having to put aside their mutual dislike for one another in order to get their best friends on the road to wedded bliss—and end up on a road themselves ... one neither of them ever expected.
