This is the hardback book Doctor Who - The End of the World, adapted by Alex Tye from a script by Russell T. The book is in very good condition, although it is missing the dust jacket (if there ever was a dust jacket).
This is plainly a fan-written novelisation and is incredibly rare (Google hasnt turned up anything of use). I have no idea how many copies were printed, and its possible this is the only one in circulation.
