Ghost by Crystal Daniels

Vengeance.
It rots, eating at his insides, seeking retribution.
Ghost lives in his own purgatory, with death as his only companion.
Until a personal vendetta leads to the discovery of a woman held captive by the man whose blood now stains his hands.
He gives her refuge from the world she feels trapped inside.
Beatrix silences his demons.
She becomes his salvation.
