Doctor Who: Forever Autumn - Mark Morris

A Halloween adventure for the Doctor and Martha set in a New England town (shades of Stephen King perhaps) that pits them against an alien race called the Hervoken. These tree like aliens use magic-like technology and fear to power their crashed ship.

As is the case with all these BBC books it was a pretty fluffy read very much based on the the tone of the TV series. The characterisation was spot on but the plot was nothing to really recommend.
