The Billionaire's Housekeeper Mistress by Australian author, Emma Darcy, is the third book in the At His Service series. When whiz-kid financier Ethan Cartwright encounters Daisy Donahue at the Magic Millions races, he's attracted, even though she's nothing like his usual women. Daisy's boss, events manager Lynda Twiggley impresses Ethan, but mostly for her mistreatment of her PA. His interference loses Daisy a job she can ill-afford to do without, but his solution is simple: she can work as his housekeeper, giving him the chance to win her heart while she does. Darcy gives the reader a feisty heroine who is not easily won and a chivalrous hero who is not easily deterred. Sparks fly in the interactions between these two, and the minor characters are fun too. This is one of Darcy's better romances.
Storyline identifies two people who come from different backgrounds but have shared the same kind of unfortunate mistrust relationships in the past, that they don't trust new people easily. Slowly each of them is able to breakdown the barriers and wash away the doubts they both had of letting another person into their life allowing them to find true, real love and happiness.
