The Collateral by Sara W. Russell

I was never supposed to be part of the deal. My father's debts were his own — until the night his creditor decided I would settle them instead. Now I belong to Damon Ashford, a man the tabloids call cold, ruthless, untouchable. A man who owns half the skyline and doesn't apologize for any of it. He brings me to his glass tower above the city and tells me, without a flicker of guilt, that I won't be leaving until the debt is paid in full — and that he intends to decide what "paid" means. I hate him. I hate that I can't stop watching his hands. I hate that when he says mine, something in me answers before I can stop it. Damon Ashford doesn't make mistakes. He calculates, he controls, he wins. But I am the one variable he can't solve — and the longer he keeps me close, the more his iron composure starts to crack. Behind the tower, the money, the reputation, is a man who has spent years making sure no one gets close enough to see what he actually is. I came here as a debt. I won't leave as one. The Collateral is a full-length, high-heat standalone romance with a guaranteed happy-ever-after. It features an intense power-imbalance dynamic that evolves into full mutual consent and partnership by the story's end — this is not a romanticization of harm; the hero's control is challenged and dismantled over the course of the book as the central relationship is built on the heroine's growing agency, not the absence of it.

Both leads are adults (28 and 34). Contains themes of coercive circumstance and power imbalance that resolve into enthusiastic consent; not intended to depict or endorse real-world non-consent.
