Darkness Surrendered — Stephanie Rowe

Six hundred years ago, Elijah Ross was tortured into insanity and thrust into a mental hell that no living creature has ever survived…except him. Now, that ancient evil is back, and it is far more deadly. Elijah is all that stands between it and the destruction of all of humanity, but each step he takes drags him ruthlessly back into the nightmare that once consumed him. Elijah's only chance is Ana Matthews, whose sensual kisses and passionate fire thrust hope and light into his blackened heart and fragmented mind. But Ana's deadly past could be the final trigger for Elijah's descent into irretrievable madness and the destruction of his soul, humanity and what is left of his heart.
