The best things in life ... can be just around the corner Rachel and Becca aren't real sisters, or so they say. They are step-sisters, living far apart, with little in common. Rachel is the successful one: happily married with three children and a big house, plus an impressive career. Artistic Becca, meanwhile, lurches from one dead-end job to another, shares a titchy flat and has given up on love. The two of them have lost touch but when Rachel doesn't come home one night, Becca is called in to help. Once there, she quickly realises that her step-sister's life is not so perfect after all: Rachel's handsome husband has moved out, her children are rebelling, and her glamorous career has taken a nosedive. Worst of all, nobody seems to have a clue where she might be. As Becca begins to untangle Rachel's secrets, she is forced to confront some uncomfortable truths about her own life, and the future seems uncertain. But sometimes happiness can be found in the most unexpected places ...
