By Joanne Harris.
A grieving woman retreats into the world of social networking, finding comfort in the traces left behind there by her dead son. Then, one afternoon, as she scrolls through her timeline, she receives an unsettling message, apparently sent from beyond the grave.
Last in a series of specially commissioned short stories inspired by the social networking phenomenon, Twitter. (For non "tweeters", the title derives from Twitter's format where "tweets" - the postings - can be no longer than 140 characters.)
