Killian by Carole Mortimer

Killian has been Natalia’s bodyguard for two years. She’s the only daughter of Leon Brunelli, the New York Mafia boss. At twenty years old, Natalia is not only wilful but dismissive of any authority. But that’s okay, because the day Natalia goes too far will also be the day she ends up over Killian’s knee and then in his bed.
Natalia has been in love with the Irishman Killian Price from the first day her father employed him as her bodyguard. A love thirty-five year old Killian doesn’t reciprocate. His disinterest leads to Natalia calling him Killjoy, and doing everything she can to annoy him. Yeah, not very mature, but there’s not much he can do about it, is there.
Until Natalia steps over an invisible line and learns exactly what Killian can and does do about it!
