Cecilia Spade is a quick witted young women Black eyes, black hair, grown long and put into stunning braids. She works as an assassin, although she was only 15. She is feared by most, though none know her name. She's taken out the poorest people to the richest there is, all by the demand of her mother.

In this story, she's given a big job, to kill a large business owner whom resided in a large mansion that shown under the glistening sun on a poppy patch just beyond a few hills. This man was known for having two twin sons who could be quite arrogant and stuck up, where as the business owner was strict but kind.

She kept getting so close to killing her target, but as a maid she had to clean rooms, do laundry, and more. She got to know the sons very well, and now her motive was different...she really liked them, but her mother would never allow it. A forbidden love with morbid origins.
