Possibly being slightly harsh in rating here, but while an enjoyable enough read, it really does come across as an abridged version of the story, suffering from the Target page count mandates, when covering a massive 10 episode story.
We do get some elaboration on characters thinking, but means that some scenes skipped altogether, and other scenes just rushed through.
As a consequence, while plenty of interesting characters featured, none really get enough screentime to really shine, and Jamie and Zoe in particular seem to suffer somewhat for this.
The story itself is an interesting one and an interesting idea, and a notable one for being the first time we are introduced to the Time Lords, and get to see Gallifrey.
Is a sad ending to Jamie and Zoe's character journeys, having their memories wiped, I like suggestions from other media that this is reversible, and was reversed eventually.
In some ways though, a fun end to the Second Doctor's run, with some very in character reactions to his trial and outcome.
All in all, not a bad story, but too condensed to be a great story.
