 This review is opinion only. A link to an episode summary is listed below.

This was an excellent Big Finish drama. It follows immediately on the tragic events of Absolution and Charlie's desire to leave after C'rizz's death feels genuine. The mystery of the other Charlie and of the ship works very well in the narrative. Charlie gets to be incredibly clever and I think these are her finest moments in the series. I've enjoyed her as the Doctor's companion. Her interaction with the Doctor has been excellent. Charlie's leaving the 8th Doctor was sad but superbly played. I think the Cybermen were used better here than in the televised series since 2005. Performances here are fantastic all around and the production is one of the best from Big Finish I've heard.
