Confessions of a Shopaholic by Sophie Kinsella (2001, Paperback, Illustrated)

This is a funny British book. While it is somewhat hard to mentally convert pounds to dollars - I found that basically doubling the amount will give you a rough idea of the outrageous amounts of Rebecca's accumulating debts! The shops visited by Rebecca may be strange to the American eye - but you can bet they are all pricey! Lost in a whirlwind of shopping and avoiding creditors Rebecca grows up when she realizes she must face up to her debts and make plans to pay them off. Her search for the best way to SL (spend less) and MMM (make more money)are often hilarious. She finds the solution and true love sheerly be serendipity. In the end Rebecca moves from sticking her head in the ground about her addiction to shopping to becoming an adult.

You'll love this book, I did!
