The first chapter of this book took a while to get in to. I really couldn't see how this would turn out to be a First Doctor story. Then I really got in to it and read the whole book in two days.

I was surprised at how well the first doctor fit into this so well. The way he slowly gained their trust, rather than going straight from being a prisoner to being their savior, was very well done.

I loved how Ben and Polly fit in so well too. I loves getting to read from their perspectives, especially in the chose your own adventure style section.

The best bit was the way it took a very adult idea like starship troopers, married it with doctor who (various different lumbering monsters, some times wimeyness, etc), married that with Agetha Christie, and had it all make sense as a cohesive and brilliant story.
