Karyn Bosnaková se narodila a vyrůstala na předměstí Chicaga. Po většinu své rané kariéry působila jako televizní producentka, v roce 2000 se přestěhovala do New Yorku a stala se spisovatelkou. Její první kniha, paměti SAVE KARYN, získala mezinárodní mediální pozornost a v roce 2003 se objevila v pořadech Today Show a 20/20. Druhá kniha Karyn a první román, 20 TIMES A LADY, byl publikován v roce 2006 a stal se předlohou pro celovečerní film "WHAT'S YOUR NUMBER?" z roku 2011. Její psaní se často zabývá tématy vztahů a sebepoznání.
What's your number?She embarks on her stalker-like search amongst the twenty former lovers, which involves walking the dog (first having to buy a dog, of course), enrolling in a cookery course, joining a gym, visiting a jail (he gets out in a month - it was worth a shot) and even checking into rehab.
What would you do if you owed USD20,000? Would you: a) Not tell your parents? b) Stop colouring your hair, having pedicures and buying Gucci? c) Start your own website that asks for money without apology? If you were Karyn Bosnak, you'd do all three...In New York for the first time, with the dream job and the smart flat, Karyn starts spending...and spending. But when it all goes horribly wrong, and her credit card balance mounts in a terrifying manner, Karyn knows that she has to take control. She starts her website www savekaryn.com on which she fearlessly asks for donations to help pay off her debts. The website receives over 2 million hits and has replies from all over the world - some supportive, many abusive. But after four months, Karyn has become a new woman- debt-free, grateful and happy. This is the hilarious and touching true story of how she does it.
