Dawn O'Porter, the wife of actor Chris O'Dowd (who called X-Factor fans racist this week), has been nominated for the Waterstones Children's Book Prize 2014 for her debut teen novel Paper Aeroplanes. Best known for her documentaries on body image, O'Porter's book was inspired by her experienced growing up in Guernsey.

Other nominees include Call the Midwife actress Emerald Fennell and performance poet Laura Dockrill for their books Shiverton Hall and Darcy Burdock. The 'age 5-12' category - which also includes Piers Torday, Sandra Greaves and Katherine Rundell - is led by the director and screenwriter Soman Cainani who will surely be considered the favourite for The School For Good and Evil, a New York Times bestseller that has already been picked up by Universal Pictures.

The prize, which rewards the winner with £5,000 (all nominees receive £2,000), will be announced on April 3.

"Our children's departments have always been the heart of our bookshops, for there, of course, book lovers are made," said James Daunt, Managing Director of Waterstones.

Daunt added: "Given the success of former winners, we can be sure they have once again identified the stars of the future."
