Magic, violence, and a little romance.  

What do you do with an unwanted lover even your pet pit doesn't like? Lady Renna hates the political infighting over who's going to rule the Marches, but her loathsome neighbor plots to use her to win his battle to become ruler. Renna becomes a political pawn and must fight to save her life when forced to use forbidden elf-fire, a capital offense.
