Priceless Pearl 

Pearl has problems holding down a job because she is so beautiful men in the offices she is employed in always fall in love with her so she keeps getting fired. After being fired from her fourth job she is having difficulty finding another one. Then her friend Augusta, who has just accepted a job as a governess, finds she can’t take up the post, and suggests Pearl should take her place (Augusta was engaged by the children’s uncle, Anthony Wood, without having met the children or their mother, and Mr Wood has conveniently gone away on business). So Pearl goes to be governess to three children who have been overindulged by their doting mother, and whose uncle is hoping a governess can bring some order into their lives. Pearl is not what they are expecting. Of course there are a lot of complications and Pearl doesn’t find her job easy. But what will happen when Mr Wood finally returns? (Goodreads)
