Ruthless Regret by L. Ann

He thought revenge would bring him peace. But what if the woman he set out to destroy is the only one who can save him?

Zain Ryder left prison with one clear objective: find the woman who testified against him and make her pay for the years stolen from him. His plan was cold, precise, and fueled by the desire for revenge. When the truth shattered his carefully crafted vengeance, Zain was left reeling—Ashley wasn’t his enemy, but a victim in the same twisted game.
Ashley may have left Zain behind, but the deadly game he’s pulled her into is far from over. Unwillingly drawn back into his world, she must confront the man who used her, and decide if she can trust him.
Zain isn’t one to give up easily. Now he has a new plan.

1. Find the real killer.
2. Protect the woman he drove away.
3. Earn back the trust he’s shattered.
The deeper Zain digs, the more dangerous the game becomes. Hidden secrets surface, and the past refuses to stay buried.

With a killer on the loose and a marriage built on betrayal and revenge, Zain and Ashley must navigate a deadly game of deception and desire. Can they learn to trust each other before it’s too late, or will the past tear them apart for good?

In this gripping conclusion to the Ruthless Games duology, the line between love and hate blurs, and redemption may come at the ultimate price.
