Lily Isabelle Andrada is a strange girl.

Nightingale is human - or would be, had it not been for the manner of her creation. Genetically engineered and grown to adulthood in a lab, she was created, not born. Why? For the sole purpose of the entertainment of rich men as one of the many Inamoratas in the bordello business . Beautiful, elegant, a superb dancer and an even better singer, she is the perfect lover for any man. Perfect, that is, except for her personality - the one thing you can't engineer.
