George R.R. Martin will be signing books at the Eason’s booksotre at 20 Donegall Place in Belfast. The signing starts at 1 PM on November 3rd. More information about the event, including a post-signing meetup, can be found at the A Song of Ice and Fire forum. The meetup will include GRRM and his partner Parris, and possibly some members of the cast and crew of HBO’s Game of Thrones production.
One additional detail is that there will be a book raffle at the post-signing moot, in support of the Children’s Literacy Charity Teachers & Writers Collaborative. Prizes are listed at the link above, and it’s probable more prizes will be added by the day of the event.
