Left hand of the devil

Cassandra is a woman in search of revenge... She hast lost her husband and her son, and she lost her arm at the hands of evil men and women. Forces of destiny conspire to turn her into an instrument of Divinity, the executing hand of Fate. 

This is a story of revenge, but also about the price we pay when we cling to hatred and resentment, how we lose a piece of our soul with every step along that path. Cassandra is a character who finds no solace, just self-destruction in the destruction of others, and she is willing to give herself over to forces she knows are dark, in order to fulfil that goal (bringing the misfortune she believes she does not deserve to others). 

Cassandra also surrenders to these forces in order to forget, to put aside the difficult choices and externalise the burden of remorse. The story centres around whether our protagonist will manage to stop in time, whether there will be anything left of her when she decides that she has reached the end of this self-destructive process.
