Campaign is an effort of the mind. It challenges the reader to think. To think about life and death and purpose. To reflect upon loss and limitation. To question the very nature of existence.
Campaign is poetry and there is no clear cut interpretation.
Telos publishing has recently announced their forthcoming series of open books written to attract a mainstream audience. It is this reviewer's understanding that these books will give respected authors more of a free reign to examine the characters and themes of Doctor Who. In this regard, I think Campaign represents a very good test subject for the potential of such novellas. Campaign is pure artistry. It's not a four act television show.
