Virtually London — Michelle L. Levigne

Athena Longfellow and Doni Halliday are granddaughters of one of Neighborlee’s guardians, Ford Longfellow. When danger threatens Neighborlee, the girls awaken to their duties and their gifts, and slowly grow into their heritage. Athena, the computer whiz, finds and experiments with an unusual video camera at Divine’s Emporium. She records Doni, and then records a room at the shop -- and inadvertently opens a door to another dimension. Properly frightened, she shuts down the program behind firewalls. Enemy invasion thwarted. For now. She doesn't realize she also created a virtual copy of Doni, until an advanced computer class in college, when the artificial intelligence that calls herself London Holiday "moves into" her team's class project. Athena suddenly has a good idea how Dr. Frankenstein felt. The question is: If she has to pull the plug on London Holiday … how?
