Little nymph / Elizabeth Stevens writing as E.J. Knox

"Two best friends, a marriage pact, and the forbidden lust that could ruin it all. My job is simple; protect Olive. Whatever she needs. Including spending the summer with the family of the man she has to marry. Maverick Vitali is anything but simple. Olive's future husband. Heir to his father's criminal empire, he's as deadly as he is gorgeous. I have one job. One. Goddamned. Job. My life is hers. So, of course I fall head over heels into lust at first sight with Mav. I could have resisted - he's an arsehole, after all - if the feeling hadn't been mutual. It takes just one inadvisable kiss for him to decide that I will be his at any cost. Luckily, Olive's had more spark with a wet towel but, when a stalker comes after her, we've all got other things on our minds than what pain Lord Vitali will inflict if Olive doesn't marry Mav. To save Olive, I'll have to team up with the man I love to hate. As the stalker grows closer, so do we. But what price will the three of us pay for Mav and me to be together?" -- Goodreads.
