Books like The Impertinent Miss Bancroft by Karla Hocker

She speaks her mind and is dismissed from several posts for it. But now, as she begins her seventh attempt as a governess, she vows that, this time, she'll control her impulsive need to be inquisitive and outspoken. Her resolve is challenged, however, on the very night she arrives at the town house of her new employer, the dashing Viscount Northrop. There, a valuable necklace is missing, and Miss Bancroft feels the thrill of pursuit stir her blood... in more ways than one. Guardian to his sister's three rambunctious children, Viscount Lucian Northrop finds himself obliged to engage a governess. Expecting the arrival of a prim and proper miss, he is surprised to encounter the incorrigible Miss Bancroft, whose quick tongue and improper notions have a startling effect on him. Though he knows he ought to dismiss her, he cannot deny that she captivates. And when danger threatens her under his own roof, he realizes he cannot let her go at all -- because he's fallen in love.
