Wilder

As a young man, Aleksandr Wilder abandoned his duty, and for that lapse, he was tortured, tormented…and transformed. Now he prowls the tunnels beneath the city, a warrior against the forces of hell, never daring to dream that he can live as a man again.

After seven years battling the world’s ultimate evil, Chosen One Charisma Fangorn has become a tough, strong fighter without illusions or joy…even her gift of hearing the earthsong has faded. Deaf to her own instincts, she never suspects that a monster lurks in the dark underneath the streets. When Aleksandr finds Charisma under attack, he rescues and cares for her, and hope stirs once more in his heart…and in the world. But could so exceptional a woman love a beast? - author's website.
