Crowne Rules is the third standalone in the Crowne Brothers.

Rich as a cardinal sin and handsome enough to piss off the devil. 

Dante Crowne has a brooding, no-nonsense attitude and a reputation for unforgettable bedroom games. When he finds Mandy in his bathtub (don't ask) he offers her a deal. Type up his notes perfectly or get a spanking. She's not much of a typist.
