Nick Barley, director of the Edinburgh International Book Festival, said : "You could say that the theme of this year’s Festival is ‘Project No Fear’.

"It’s about encouraging and celebrating the sort of courageous, positive, creative thinking that we desperately need in order to make the world a better place for everyone, rather than just for a privileged few.

"Novelists, journalists, scientists and poets – writers are the people we always turn to at a time when we need to imagine better.

"We welcome legendary novelists, prize-winning journalists and life-changing poets, as well as emerging talents whose unforgettable stories will revolutionise our future thinking. All in all, it’s a festival bursting at the seams with big ideas."
