Everyone knows Reid Greco is the Don's heir. No one notices the girl standing beside him. Rescued by the Greco family as a child, Karla grows up at Reid's side. For thirteen years, she follows him everywhere—through training, bloodshed, and the dangerous world of the Greco empire. She becomes his shadow.

The problem with living in someone's shadow is forgetting where you end and they begin. Karla knows Reid better than anyone. She knows the brilliant strategist hidden beneath his careless playboy act. She knows the future Don the rest of the family fails to see. What she doesn't know is how to stop loving him.

When Reid is pushed toward an arranged marriage, Karla decides it's finally time to step back.

But the moment she starts pulling away, Reid begins to realize something terrifying: his shadow may have been holding his world together all along.
