George RR Martin has joined a growing band of science fiction and fantasy writers who are coming together in support of Terry Pratchett and Alzheimer’s Research. Terry Pratchett was diagnosed with the disease at the end of 2007 and has since donated almost half a million pounds to the cause. George RR Martin has donated many rare and signed books for auction with all proceeds going to the campaign.

Donations can be made to the Alzheimer’s Research Trust here - http://www.alzheimers-research.org.uk/. There is also a message from Terry Pratchett on the homepage.

Pat Cadigan has launched an official ‘Match It For Pratchett’ campaign with the hope of raising half a million pounds to match Terry Pratchett’s recent donation.
