Mind Pirate - Inception

Donald Cooper, at sixty-five years of age, a high-powered top banker for various mobsters, suffers a severe heart attack and realizes that he is about to die. A split second before his body expires, his mind, which is abnormally evolved, escapes its physical confines and penetrates the body of a young woman, eliminates her mind, and finds a new home.
He had never known his mind's true capacity, but, once ensconced in Jessica's body, Donald accepts his new place in the world as a young female. However, since Jessica had led a rather unsavory lifestyle and had a police record as a result, he creates for himself a new and unshakeable identity--hence the birth of Lucille Holloway.
Lucy quickly becomes enamoured with her new and thrilling life as a young woman and undergoes many adventures as she develops a social circle of devoted friends and becomes financially established.
