From book cover:
Shoppen macht glücklich!
Becky Bloomwood schwebt im siebten Himmel. Sie ist mit Luke Brandon, dem Mann ihrer Träume, auf Hochzeitsreise rund um die Welt, und natürlich kommt dabei auch das Shoppen nicht zu kurz. Wieder in London landet sie allerdings unsanft auf dem Boden der Realität. Sie hat keinen Job, Luke ist wegen ihrer überzogenen Konten sauer und ihre beste Freudin Suze hat eine neue Busenfreundin. Da taucht Jessica auf, eine Schwester, von deren Existenz Becky nichts wusste. Eine Schwester - eine Seelenverwandte! Ein Geizkragen? Becky ist fassungslos...

From sophiekinsella.co.uk:
Sophie’s introduction:
“I think the Becky-Jess double act is a really fascinating relationship, and I loved creating it.
The story begins on honeymoon, where Becky is displaying her usual reserve about buying souvenirs (ie buying everything in sight, shipping it home and forgetting about it). She and Luke are ready to come back to England and begin married life properly. But when they arrive, they’re in for a shock as they discover that Becky has a long-lost half sister, Jess.
She couldn’t be more excited. At last, a real sister! Someone to go shopping with, be girly with, have manicures with… Until she meets her – and her shock is complete. Surely her own sister can’t… hate shopping?
Jess is ethical, puritanical and serious-minded. She doesn’t paint her nails. She doesn’t watch rom coms. Do she and Becky have anything in common…?
The story of Becky and Jess is almost like a romance. Hate, love, hate, love… they go through a rollercoaster as they both try to get used to the idea of having a sister they never knew about. The story ends up with Becky embarking on perhaps her most foolhardy, extreme adventure ever, and was very exciting to write!”
