Shopaholic & Sister

What's a round-the-world honeymoon if you can't buy the odd souvenir to ship back home? Like the twenty silk dressing gowns Becky Brandon (nEe Bloomwood) finds in Hong Kong, or the hand-carved dining table from Sri Lanka, or the, um, huge wooden giraffes from Malawi (that her husband expressly forbade her to buy). Only now Becky and Luke have returned home to London, where two truckloads of those souvenirs have cluttered up their loft. The bills are outrageous, Luke is furious, and Becky's feeling rather blue--until her parents deliver some incredible news. She has a long-lost sister! Becky is convinced her sister will be a true soulmate. They'll go shopping together, drink cappuccinos together, get manicures together. Then Becky meets Jessica and receives the shock of her life. Surely the shopaholic's own sister can't "hate""shopping"?
