Confessions of a Shopaholic by Sophie Kinsella

Shopping addict and financial writer Becky Bloomwood works for Successful Savings, a second-rate trade magazine. Becky, for whom saving is a concept for other people, relieves the tedium of meaningless work with giddy sprees she can ill afford. As her debt grows ever more unmanageable, Becky's self-justifying obbligatos become ever more shrill, and her white lies turn steadily darker. In one self-delusional attempt to find a better paying job, she bolsters her resume with fluency in Finnish, only to come face to face with the CEO of the Bank of Helsinki. But when Becky gets her teeth into a real news story, she discovers her limits are far greater than she had imagined.

Meanwhile, perky flatmate Suze, the daughter of fabulously rich and indulgent parents, is little help, although she does fix Rebecca up with her equally wealthy cousin, Tarquin Cleath-Stuart. Dreaming wistfully of marrying money, Rebecca tries to impress the dull but sincere Tarquin by inventing a charity that provides violins for impoverished children in Mozambique—and is mortified when he immediately makes a donation of five thousand pounds, scribbling a cheque that she has to return. But there's another man in her future: handsome Luke Brandon, a financial genius who devised a fund-switching scheme that seems to have deprived her parents' neighbors—a well-meaning but slightly dotty old couple—of their nest egg.

My co-worker loves this series so I thought I would give it a try. Fun, but the characters really don't make me want to read more in the series. I would rather read Bridget Jones Diary books instead.
