Before embarking on Castle Waiting, Medley worked in the comics industry as a penciller, inker, painter, colorist, and sculptor.
Her pencilling work includes stints on DC Comics' Justice League America (1991) and Doom Patrol (1993), as well as the Galactic Girl Guides for Tundra Press.
Her paintings have appeared on the covers of Paradox Press's Family Man, Howard Cruse's Stuck Rubber Baby, and TSR, Inc.'s Dragon magazine.
Medley illustrates Castle Waiting in a style reminiscent of the work of Arthur Rackham and William Heath Robinson.
Medley is currently working on a series of nine graphic novels based on L. Frank Baum's Wizard of Oz books.
