It's a curious but little known 'fact' that the younger brother of Jesus is Justin Bieber.

His story will be revealed on Saturday in The Book of Bieb via 241 Tweets from no less an authority than God himself (@TheTweetOfGod). A relatively popular deity, God has 1.25 million followers but follows only one other person – the Bieb himself.

It's all part of the second Twitter Fiction Festival (@twfictionfest) and the brainchild of author David Javerbaum, whose @TheTweetOfGod tweets have been enraging and entertaining in equal measure for the past three years.

“God has been grabbing headlines ever since first creating the universe,” says Javerbaum/God in advance publicity for the new work. “His previous serious works as an author, the Old Testament, the New Testament, and the Koran, have sold an impressive 5 billion copies, with the first two in particular coming to be collectively regarded as something of a bible of their field.”

iTunes describes The Book of Bieb as: "A new book of the Bible devoted to the unholy life and times of Justin Bieber, penned by the Bieb's #1 fan and popular Twitter personality."

Other big name writers who are spinning yarns in 140 characters or fewer for the Twitter festival include Alexander McCall-Smith, author of the best-selling the No.1 Ladies' Detective Agency series, Graeme Simsion who wrote the massive hit The Rosie Project and Andrea Cremer, author of the bestselling Nightshade series.

Alongside the 25 recognised authors, another 25 competition winners are tweeting out their stories in the five-day virtual festival. From romance to science-fiction and horror to poetry, no genre will go untweeted.

And, this being Twitter, there is plenty of opportunity for interaction with readers and creative uses of the medium.

“We love fiction that uses Twitter functionality in the most creative way possible,” say the organisers. “That means perhaps something more than just tweeting out a narrative line-by-line.”

Techniques that have been used in “Twitterature” include creating multiple accounts for characters, who then interact online; crowd-sourcing to create a collaborative story; and setting up parody accounts.
