Relative takes place just prior to An Unearthly Child and involves Susan and several of her classmates from Coal Hill School trying to survive an alien invasion of Earth by a race of ice beings called the Cold and at the same time convince the Doctor to stop the attack. In the 2003 Telos novella Frayed, which also takes place prior to the serial An Unearthly Child, Susan's name was given to her from a young girl in a besieged human medical facility on another planet, after the girl's mother. The Eighth Doctor Adventures novel Sometime Never... depicts the Doctor's adoptive granddaughter Zezanne as an alien princess who would later travel to a junkyard in 1963 with a man who resembled the First Doctor. In the 2017 novel A Brief History of Time Lords, an image of Susan is shown as one of the things that the Doctor took with him when leaving Gallifrey, although she is listed as the President's daughter. Susan also appears, played by Ford, in the Companion Chronicles audio drama series from Big Finish. Quinnis (2010) takes place before the television series, when the Doctor and Susan were traveling alone. In the Big Finish bonus release An Earthly Child (2010), Susan is reunited with the Doctor in his eighth incarnation (Paul McGann), and has a son named Alex (Jake McGann). She appears in the Eighth Doctor Adventures audio plays in Relative Dimensions (2010) and Lucie Miller / To the Death (2011). In the later Short Trip "All Hands on Deck", Susan decides to leave her life on Earth and join the Time War, with the box set Susan's War depicting her service in the War. She helps the Time Lords form an alliance with the Sensorites to gain the aid of their telepathic circuits- also recruiting Ian to act as a diplomat in the process- ("Sphere of Influence") and later missions including capturing a Dalek agent on Florana ("The Uncertain Shore") and preventing a plan to configure the vortex-dwelling Orovix as a weapon against the Daleks as Susan recognised that they were too dangerous ("Assets of War"). She was briefly manipulated by a Dalek agent to go back to 1963 to try and help them retrieve the Hand of Omega before the Hand could be used to destroy Skaro, but she and the Eighth Doctor are able to trick the Daleks into taking a fake Hand
