Unforgiven - Grace Sufficient, #4

Redemption isn't free. Guilty of countless crimes, Vladislav Genkin is desperate to find forgiveness. Violence has long scarred his soul, and his sins push him to Grace Baptist Church to confront Nikolai Alexandrov, one of his victims. Yet Nikolai's forgiveness brings Vlad no peace, and against Vlad's will, he's drawn into the circle of the church and Nikolai's dangerous past. Katya Voronova rebuilt her life from the shambles of a long-ago divorce, and Vlad's appearance leaves her shaken and besieged by memories better left untouched.
Yet she is drawn into the rising danger, and Vlad's past becomes more apparent-and unforgivable. As the past finally catches up to Vlad and Katya, will they find the forgiveness they crave-and will they discover that grace has already accomplished it?
