I found the POV, third-person omniscient, rather distracting. The point of view changes from one sentence to the next and that really jerked me out of the story. If the switch happened at chapter boundaries, it would be better. Worse, the "head hopping" from the thoughts of one character to another included several characters ay the beginning of the story, but only a couple at the end. What was the purpose then? I suffered through the maze of all those thoughts at the start when nothing was happening but never got to know how they felt at the end about how it all turned out.
The conflict is not spelled out well at all. Is it man vs. man or man vs. nature? (view spoiler)
I have read a great deal of Michael Moorcock's books. He effectively took his back story for his other series like Elric or Eternal Champion and stuck the Doctor in the middle of it. Perhaps a Dr. Who fan might not be troubled by that if they hadn't read Moorcock's other works, but it doesn't really fit well with the Dr. Who universe anyway. In the past, the Doctor has travelled to E-Space, but I don't recognize any of the planes of existence in this book.
The author did do a great job of getting the dialog right between the Doctor and Amy.
