After a short time, she left the band, but quickly found work doing voice-overs while composing scores with her husband for Coronet Films.

Campbell has said the staff of computer games company Blizzard Entertainment saw this performance and requested her services to add voice-overs for a collection of characters from Diablo and StarCraft.

[citation needed] Besides voice acting, Campbell is a historical romance novel writer and has been nominated for a number of literature awards.

Her romance novel, Captured By Desire, is set in Mary, Queen of Scots-era Scotland, and was released August 2010, followed by Seduced by Destiny in March 2011.

She worked extensively on a collection of audiobooks for Time Warner including those in the Star Wars Tales of the Jedi and Dark Empire series.
