Freebie from Harlequin. You get what you pay for. This romance combines the mistaken-identity trope with the bachelor auction plot device. When the heroine bids (overbids, seriously overbids) at a charity bachelor auction, she thinks she is preventing her stepmother from purchasing the services of a Eurotrash gigolo. He is really a Chicago firefighter (victim of a clerical error at the auction), but she doesn't realize this throughout most of the book, despite all the clues staring her in the face, because she is either stupid or never pays much attention to anything despite supposedly being a big-shot banker. On the other hand, this book does have a rather dramatic brawl-at-a-wedding-rehearsal-dinner scene which was worth a few cents more than the $0.00 I paid for this book.
