Rosen is quoted as saying: “”If there had been a prize for funny books when Roald Dahl was writing, he would have won it with every book he wrote. That’s why this award was named in his honour. Children love funny books but when adults draw up lists of the best books they nearly always leave the funny ones out.”

Which is why Rosen created the prize.

There will be two separate categories for the prize: books for children six years and under, and books for children seven to fourteen years’ old. The shortlist will be announced on Roald Dahl Day (September 13). The prize is £2,500.
