Her biggest heartache? She's been secretly in love with her boss for years... A hapless personal assistant needs to preserve her sanity, and she can't do that while working for her ruthless billionaire boss. Jaw-droppingly handsome, Jett Knight relies on Cari for pretty much everything. If she's not picking up sexy lingerie and expensive designer trinkets for his girlfriends, she's making dinner reservations and travel bookings for him and his lovers. All while suffering in secret and watching from the sidelines. This single dad is older and out of her league. Worse, he doesn't even notice her. Not in the way she wishes he would. But at least his cute four-year-old adores Cari. She's stuck for now. This job provides many perks, such as the health insurance her mom desperately needs. But what Cari desperately needs is to get Jett Knight out of her system. THE DARKEST KNIGHT is the prequel to KNIGHT EMPIRE, a new steamy billionaire series featuring a family of six billionaire brothers and a cold and manipulative father at the helm of a billionaire empire.
