More Than a Millionaire

I remember reading this book years ago and I enjoy story the characters are telling me too

Description from the book back cover: Moving in with a millionaire! Emilio Diz, born on the wrong side of Buenos Aires, was now a tall, dark, irresistible millionaire. And he needed a woman - the right kind of woman - in his life ... or at least in his apartment! Abby, aka Lady Abigail Templeton-Burke, was desperate for somewhere to live. Who better to help furnish Emilio's new London penthouse and create the right impression? There was only one problem with Emilio's convenient flatmate: she was driving him crazy - with desire!
