Descendants of British literary lions Charles Dickens and J.R.R. Tolkien are collaborating on a pair of fantasy novels and audiobooks, their publishers said. The BBC said Gerald Dickens, the great-great grandson of Charles, will narrate the audiobook versions of \"Wish\" and \"Rainbow\" -- books penned by poet Michael Tolkien and due to be released later this year by Publisher Thames River Press. J.R.R. Tolkien, Michael\'s grandfather, wrote \"The Lord of the Rings\" trilogy and \"The Hobbit.\" Charles Dickens\' works include \"Oliver Twist,\" \"Great Expectations,\" \"A Christmas Carol\" and \"A Tale of Two Cities.\"
