This is a Doctor Who novel but it's not like any of the others. It does feature the Doctor in his Tenth incarnation with Martha Jones, but here the main character is actually Martha! I think this book sums up exactly what a Doctor Who novel should be: it takes an event that's mentioned in the show and expands on it. I think there are a couple of other novels that have done this, where there's a throw-away line in an episode which mentions an adventure that's never actually shown but it becomes the plot of a book instead and we get to experience it that way. I was rather looking forward to reading this particular book because it's nice to be able to find out what happened to Martha during the Year That Never Was. Although it's not the Official story as such because it doesn't come from Russell T Davies, it's a good alternative.
The book is credited to Dan Abnett but he isn't the sole author. He wrote the main storyline that runs through the book and follows Martha in her trip round the world. Along the way, she tells of adventures she has had with the Doctor and these adventures are all written by different people. It's quite well done and hard to tell the different authors as there's no obvious jump in writing styles. I did feel that the book wasn't long enough, the adventures that Martha shared were only very short and it didn't seem as though they were enough to convince anyone how amazing the Doctor is.
I was really enjoying the book until Martha got to Japan where the story seemed to forget what it was supposed to be about and deviated from the original storyline. Martha gets captured in Japan because the perception filter becomes extremely dodgy. Just as she is in danger it randomly stops working all of a sudden and only starts working again when the factories are destroyed and she is free again. That didn't make sense at all and is laughably convenient. Considering the entire book up to that point was showing how Martha was Enemy Number One and had to be captured at all costs, it then didn't seem feasible that she would be captured and not returned to the Master. This was explained by saying that Japan wasn't under the Master's rule which again doesn't make sense and goes against the plot of the episode that the book is related to. There's no indication of exactly how long Martha is held captive but it seems to be quite lengthy and I got the impression it was several weeks. It doesn't seem possible that she could spend that amount of time there and still have enough of the year left to see the rest of the world, bearing in mind at this point, she's only done mainland Europe.
The reason given for Japan not being under the control of the Master is that the factories there are controlled by the Drast. This is another bunch of aliens who have crashed onto Earth and are trying to get off it. I couldn't believe this bit, there was no reason to introduce these aliens. As if the Master wasn't enough to contend with - and judging by the episodes of the show, he really was - there's now an alien invasion to deal with as well. It was just a bit much and seemed as if the author(s) got bored with the Year That Never Was storyline and decided to write something else instead. And after all that, the way the Drast were made to surrender was a bit puerile.
The final section of the book just didn't make sense at all and I spent the entire time boggling at it in disbelief. The book as a whole needed more of the Master in it, and not some random bloke who was chasing Martha. He was then blown up by the Toclafane at the end, something else that made no sense. The Master was mentioned only rarely and seemed to be a distant threat. It didn't come across as though there was any real danger from the Master right until the end when he ordered the destruction of Japan. At that point, there were only a few pages left so it was much too late. There didn't seem to be much sense of urgency or danger from the random bloke who was chasing Martha either and any threat seemed to be more from the fact that he was a bit mentally unstable than anything else.
