They sent the president’s son to babysit me.
How precious.
Shepherd “Shep” Winchester III thinks he’s here to keep me in line—keep me quiet, keep me still, keep me safe.
Good luck with that.
I’m Theodore “Theo” Rinaldi, the youngest Prince of Monaco, and the most merciless of the Park Avenue Kings. And I don’t do obedient. Not for my royal family. Not for the crown. And definitely not for the suit King sent to shadow me.
