I'd heard a lot about Mike Tucker and Robert Perry's writing so I was sort of expecting a nigh-on masterpiece, and by jove, for me, this book comes very close to it. Sure it had the Cybermen (old hat enemies of the Doctor) but the way they were incorporated into the story I thought was ingenious.
All of the characters were fully formed, three dimensional beings, not one of them a cardboard cut out and I even felt like Ace and had some sympathy for George Limb, especially at the beginning, because as the Doctor said, (something like) "He wasn't really an evil man", but boy did he cause so much havoc or what? Actually, to be honest, the Limb character reminded me of a somewhat diluted Master, if the Master was human of course. *shrug*
In all honesty, I'm not a fan of gratuitous violence where the only purpose it seems to serve is to end someone's life, so I was more than pleased to see that the violence in this book carried a rather stark and depressing message alongside of it.
All in all, this was indeed a fast paced, action packed book, but with its quieter moments you got to sink your teeth into a wonderful story, which included a slightly more than aesthetic look at what it might have been like in London during WWII and a theorising of a possible future when it comes to 'Cybertechnology'. Very nice indeed.
So, five stars from me and a very high recommendation. Now onto "Loving the Alien" - I can't wait :D
