Shopaholic Takes Manhattan (#2) by Sophie Kinsella

With her shopping excesses (somewhat) in check and her career as a TV financial guru thriving, Becky's biggest problem seems to be tearing her entrepreneur boyfriend, Luke, away from work for a romantic country weekend. And worse, figuring out how to pack light. But packing takes on a whole new meaning when Luke announces he's moving to New York for business- and he askes Becky to go with him!  Before you can say "Prada sample sale," Becky has landed in the Big Apple, home of Park Avenue penthouses and luxury boutiques. 

Surly it's only a matter  of time until she becomes and American TV celebrity, and she and Luke are the toast of Gotham society. Nothing can stand in their way, especially with Becky's bills  miles away in London. But then an unexpected disaster threatens her career prospects, her relationship with Luke, and her available credit line! Shopaholic Takes Manhattan- but will she have to return it?
