King of Scars

In this dark fantasy, King Nikolai Lantsov harbors a demon that transforms him into a winged monster. The female general Zoya Nazyalensky—the woman he passionately loves but resists because of the evil which lurks inside him—helps the stricken monarch control the destructive beast and hide his ugly secret from the unsuspecting kingdom.

I loved how King Nikolai struggled with the monster within, finally accepting it as the darker half of his own soul and a source of immense strength for him as king. I also loved how the monster--a most unlikely romantic hero—knew Zoya and protected her, like Nikolai himself.
