Shadow Planet (audio story)

 was a full cast audio story released on 13 June 2017 by Big Finish Productions. Shorter than the vast majority of stories in the Doctor Who monthly range, it appeared alongside World Apart.

Like Alien Heart, Shadow Planet ended in a cliffhanger leading directly to World Apart
