Andi is among a group of University students who were taught a way to magically change themselves into wolves by Tera West.
In Fool Moon, she is described as a shy, plump redhead, which filled out her robe a little too generously, new at shapeshifting and who arkwardly covered herself with her arms, shedding her dress and chanting the spell to change into her wolf-form, a round, hefty-looking with dark auburn fur animal.
In Summer Knight, she had slimmed down due to the heavy exercise in her work with the Alphas, gaining a figure described as being out of a men's magazine.
In Summer Knight, she is still unnamed and among the wolves that go with Harry Dresden to the Fae War at the Stone Table. As she is getting anti-glamour ointment applied, Marcy (unnamed here, only described as petite, with mousy brown hair) complains that she's been impossible all year because her new slim and beautiful looks.
In Turn Coat, Andi is injured by the Naagloshii, Shagnasty, who killed Kirby, who by now was her boyfriend. It takes two rounds of surgery to stop the internal bleeding. Harry Dresden visits the Hospital where she is in ICU.
In Aftermath, she and another ex-Alpha, Marcy, have been keeping the pregnant Georgia company while Billy was out of town. She and Georgia are kidnapped by an unknown faction—the Fomor—but Karrin Murphy, Billy, and Marcy free them.
