With all those maxed-out credit cards, Becky has everything – except a sister. But then she learns about a long-lost half-sister, surely someone to shop with and trade clothes with. But wait – this new relative hates to shop! How could she be related to Becky? Fourth in the series. "Kellgren's vivacious reading never fails to plumb the depths of Becky's despair... hilarious mayhem... pure fun."—Publishers Weekly
