Whoohoo! I did it! They Feed On Flesh finally ended on 50,893 words and took my zombies from the initial outbreak of the plague (discovered in an unknown tomb in The Valley Of The Kings in Egypt) to Britain, then the rest of the world, onwards to Mars and finally back in time to another version of Earth.
Phew... the most I've ever written in one go and now I need to go lie down in a dark room for a year or two...
Anyone out there interested in publishing a zombie romp?
