Timewyrm: Revelation

Blurb

Timewyrm: Revelation is an original Doctor Who novel, published by Virgin Publishing in their New Adventures range of Doctor Who novels. It features the Seventh Doctor and Ace, as well as cameo appearances by the Doctor's mental representations of his first, third, fourth and fifth incarnations.
This is the first novel to feature a personification of Death, who turns out to be one of the Eternals, and sets the scene for future New Adventures in which the Doctor becomes Time's Champion. Death has also crossed over into the Big Finish Productions audio dramas; in Master, the Master is described as Death's Champion. The novel is also the final part of the Timewyrm quartet. It has been described as the point at which "the books entered adult terrain".
