Personally, all I can say is I couldn't put it down. The 3rd in the Princess Brides series about the youngest sister Joelle and Leo. Strong Alpha male, whom I adored.

Harlequin's Book Summary:
Princess Joelle Ducasse must marry the man who has been chosen for her. Joelle knows her marriage will be one of duty, not love. So in an act of defiance she decides to spend one hot, steamy night with a gorgeous stranger. But unbeknownst to Joelle that stranger is actually Prince Leo Borgarde - her future husband!

Leo is furious that his future wife could behave in such a reckless way. He demands that Joelle must be punished, and he knows just the right way...by marriage ( )
