His love of creative writing flourished even in jail and led to Morrison's first novel, 'West Belfast,' being published in 1989 but never formally launched.
In 2015 a revised edition was re-issued to celebrate the 25th anniversary of the first publication. 'On the Back of the Swallow,' his second novel, was written in prison and published nine months before his release, in May 1995.
'The Wrong Man,' his third novel, also begun in prison, was completed after his release and published in 1997. Morrison's three works of non-fiction are: 'Then The Walls Came Down,' based on his prison letters, published in 1999; 'All The Dead Voices,' a part-memoir, published in 2002; and 'Rebel Columns,' a collection of his political writings, published in 2004.
He edited a book of essays, 'Hunger Strike,' which was published in 2006 by Brandon. His fourth novel, 'Rudi – In the Shadow of Knulp,' inspired by 'Knulp,' the 1915 novel by Hermann Hesse, was published in 2013.
