Like Birthright this was adapted from a Virgin New Adventures novel, rather than from a Virgin Bernice Summerfield New Adventures which featured Bernice without the Doctor. The original novel of Just War featured the Seventh Doctor, Bernice Summerfield, Chris Cwej and Roz Forrester. For this audio adapation Bernice's role remains intact, whilst Jason Kane takes on a combination of the other characters' roles in the plot.
