I will firstly say that this was the first ever Doctor Who audio book I have listened to. But I must say that I didn't enjoy it. The story starts off promising but unfortunately by the end it slightly went off course and made it uninteresting.
The writing is okay, the characters of The Doctor, Amy and Rory are captured perfectly well and are read excellently by Alexander Armstrong who without impersonating them makes it a good listen. His voice works perfectly, its just a shame the story didn't match up to it.
