Diamond (Diamond Trilogy Series #1)

Black Lace: the leading erotic imprint for women.
     Jenna Myatt has a famous name but, since splitting with her heart-throb pop star husband, she is desperate to make her own way in the world and buys a crumbling old house in the neighbourhood she grew up in. 
     At Holderness Hall she is met with a mysterious man, who only goes by the name of Leonardo. Intrigued — and attracted — by him, Jenna agrees to let him stay as long as he help her with renovations and fixing up the house. 
     There is a strong attraction between them, although he has a massive chip on his shoulder about her wealth and connections. And despite being younger than Jenna, he has a lot to teach her about sexual pleasure.
