Hot off the success of her bestselling CAN YOU KEEP A SECRET?, Sophie Kinsella delivers another hilarious Becky Bloomwood novel. When last we left Becky Brandon (nee Bloomwood), she and Luke had just married and she'd unveiled her big honeymoon surprise...around-the-globe plane tickets. World-weary ten months later, the newlyweds return home filled with excitement to share the details of their amazing escapades. But their arrival brings a different sort of homecoming, as Becky discovers some unbelievable news: She has a sister. Ok, a half-sister, but a sister nonetheless. Someone to share with, to have manicures with, to shop with! But, can it be, that Becky's long-lost sister hates to shop? Hates to spend, really. And is fascinated by rocks...not diamonds.
