I enjoyed listening to John Connolly on R4's Today programme this morning, Friday 9 October. You can catch him on Listen Again - push the timer along to about 2.47 mins into the programme. He was talking with John Humphries about his latest book and then the dreaded word Crossover happened and here is a rough transcription of what was said:
John H: Crossover books are meant to appeal to both children and adults
John C: That's a word if any author used they should be beaten with a big stick. It is a marketing exercise...cynicism...books that are aimed to draw in an adult readership and to do that you have to wink over the shoulder of the children to the adults.
John H: You patronise the adults or you go over the head of the child
John C: You patronise both. You infantalise the adult and you patronise the child so everyone loses out.
