The Debt by Linzi Basset

Some debts can only be paid in blood…

Twenty years ago, my world died on an Atlanta street. One bullet. One moment. One man who didn’t even spare a glance at the lives he destroyed.
I become something that makes monsters check their closets at night. Each calculated step brings me closer to the debt Gregor Polov owes—a debt written in the blood of innocents.
In this dark tale of revenge, redemption remains a distant dream. For when I dove into the abyss to become the very thing I hate, I realized the only way out is through more darkness.
Some debts can never be forgiven. Some souls can never be saved.
But Jarek Farrel soon realizes that in a game where power and violence reigns… even the most carefully laid plans can unravel. Polov is a master at the games powerful men play, and Jarek quickly learns that some debts create deeper wounds when they’re repaid.
I am willing to pay any price—use an innocent woman—to settle the score… Even if it destroys the little humanity I have left.
The Sordid Debt Duet will drag you into the shadows where morality blurs, justice bleeds, and the line between vengeance and redemption dissolves into nothing but crimson mist.
