Right Number, Wrong Girl

Taking a work call for my best friend in my undies? Check.
Filling in for her after an emergency and getting mistaken for her? Check.
Royally messing it all up until the hot duke-in-waiting I hate but can't keep my hands off steps in to save me? Uh, check... Yes, yes, that all sounds wonderful, doesn't it? Until you consider I now have to plan and execute an 80th birthday party for The Dowager Duchess of Devon, and I can't organise my hairbrushes. The current duchess is the ultimate Type-A personality, determined to micromanage the entire thing.
I'm a type... XYZ...LMNOP... Maybe not even that.
When all my attempts go to hell in half a handbasket-I can't even mess up properly-the only hope I have to pull this thing off is duke-in-waiting Hugo Edwards.
The dreamy, handsome, makes-my-heart-pitter-patter, arrogant tosspot Hugo Edwards.
He and his brother are the only people who know who I really am. The success of their grandmother's party relies on us getting along long enough to make it happen-and me and Hugo keeping our hands off one another behind closed doors.
None of which is easy to achieve.
When my best friend shows up to take over from me, the fact that I've fallen for Hugo is the least of my worries...
