Eloisa James 
Duke is Mine [EPUB ebook] 
Number 3 in series

‘Nothing gets me to a bookstore faster than Eloisa James’ – Julia Quinn Once upon a time, not so very long ago…Tarquin, the powerful Duke of Sconce, knows perfectly well that the decorous and fashionably slender Georgiana Lytton will make him a proper duchess. So why can’t he stop thinking about her twin sister, the curvy, headstrong, and altogether unconventional Olivia? Not only is Olivia betrothed to another man, but their improper – albeit intoxicating – flirtation makes her unsuitability all the more clear. Determined to make a perfect match, he methodically cuts Olivia from his thoughts, allowing logic and duty to triumph over passion . . . until, in his darkest hour, Tarquin begins to question whether perfection has anything to do with love. To win Olivia’s hand he would have to give up all the beliefs he holds most dear, and surrender heart, body and soul – but it may already be too late.’Eloisa James is extraordinary’ – Lisa Kleypas’Romance writing does not get much better than this’ – People
