A Dark Most Fair by L M Riviere

You should know, I did it. Before you trouble yourself to read any further, you won't find an innocent woman in these pages. I am every bit as evil as they say I am. A murderer. A liar. A kinslayer. The gods, they say, save their worst punishments for those like me. Those who covet what isn't theirs. Those who slay their own blood. Those who lie about it after.I'm a woman who murdered for a man. There isn't a hell black enough for one such as me. I'm every inch a sinner. And I will get what I deserve. Soon.
