I actually rather liked The Roof of the World; even though the good bits are all stolen from other Doctor Who stories (apart from the nods to Lovecraft) I liked the development of Erimem's character, and Davison and Bryant got good chances to do their stuff; plus the setting was on the whole very well depicted given the audio environment. I was rather astonished to find out the back-story of the author after I did a little googling... ( )
