The Art of Ruin by L. Knight

I took a job as a live-in nanny for a billionaire single dad to escape my old life.
After discovering my fiancé’s affair—and the baby he kept hidden from me—I leave LA for Manhattan determined to keep my head down, heal quietly, and avoid complicated men altogether.
Then I meet Adriano Mancini.
My new boss is possessive, protective, and impossible to ignore. He loves his daughter fiercely, watches me like I’m something precious, and somehow sees through every wall I try to keep in place.
Living in Adriano’s brownstone was never supposed to feel like home.
Neither was falling for him.
But just when I finally start believing I deserve something real, my past comes back determined to destroy it—and Adriano’s need to protect me starts blurring into secrets and control in ways that threaten everything between us.
