Yanga la Reina de las Tinieblas #1

Marta del Castillo is deemed ugly by everyone including herself. Despite being a brilliant young PhD chemistry professor, Marta desires the kind of life her looks deny her. One night, Marta makes a concoction in lab that turns her into a beautiful redhead. She kills a university guard who catches her before going dancing with two stockbrokers. To her dismay, her appearance reverts to normal after 2-3 hours forcing her to flee a lover's apartment to return to the lab. Marta navigates through the police investigating her earlier murder to make more serum so she can become Yanga again.
