Doctor Who: The Graves of Mordane

Review from 2012.
This book is set just after book one. We see how the cliffhanger at the end of The Dust of Ages is resolved and how the Doctor finds the next clue to the mystery of the Eternity Crystal. This leads him to Mordane where the he sees how much the planet has changed. Children may not see it until it is revealed, but it is soon clear what the Crystal does and why several people want to have it.
As it happens with the other book of this series, we’re supposed to know the Doctor and not much information is given about him.
There is some character development though. Catz starts as just a young girl, but we soon discover that not everything about her is what we had assumed. The other characters are a bit flat and their characterization doesn’t include many details.
The action is fast-paced and the activities are easy, though also fun. This book doesn’t end with a cliffhanger, like the previous one, but not all the questions are answered (and we have new ones), which keeps the audience interested.
The target audience of the series is young people, but although it is rather short, older Doctor Who fans can enjoy it, too.
