Used book – Baby-sitter, quelle galère !, Betsy Haynes

Of course, Rosie should never have borrowed her sister's mountain bike without permission. Because of her, it's now good for the scrapyard. And to pay for it, Rosie has to take a job she absolutely hates: babysitting for the Pandrauds. But why is Rosie never allowed to see the baby? Something is wrong in that house!
