Marigold and Mayhem by Ember Davis

SERGIO VITALE
I live and breathe for the Agosti family. After being the cause of Elio almost losing his queen, I owe them nothing less than my life. I can’t change what happened that day, but I can make sure it doesn’t happen again. I’m resolute in my responsibilities, until I see her—a flower amidst the darkness.
She is too innocent for the world and doesn’t see the danger lurking around her, but I do. The man who wants to buy her grandfather’s bookstore won’t play fair; men like him only know how to take and destroy. I won’t let him do that to my Marigold.
I bring chaos into her world, but I’ll show her there is beauty to be found within my protection. I won’t let anything come between us. I’ll become her beast because it is the only way to ensure she’s never tainted by the blood that stains my hands. They can come, but they’ll never win.
