Noble Prince by Sidney Bristol

A princess enslaved to her mother’s company, a prince at the end of his rope, a fairy godmother racing against the clock, and an enemy who wants them all dead… Quinn Schaeffer needs two more weeks. If she can display her new invention at the upcoming conference, she might just save her dearly departed mother’s company. But there are people who are willing to kill to keep Quinn quiet. Owen King has lost it all. His livelihood. His dream. Everything that makes him tick. That is, until he interrupts a home invasion and saves her. The most prickly, beautiful woman he’s ever had the pleasure of putting up with. His new mission in life: Keep Quinn Safe. Someone is after Quinn, and that same someone wants to make Owen pay. Together, Quinn and Owen will have to solve the mystery behind her mother’s invention in order to figure out who wants them both dead.
